Only a simple traditional design method of {MMI} based on self-imaging theory and a single-stripe Si3N4 waveguide geometry with only one step etching process are utilized. The characterization of the fabricated devices is carried out over a wide spectral window of 1520–1610 nm, showing that the measured phase error is less than 8◦, and common-mode rejection ratios ({CMRRs}) are better than −20 {dB}. The measured total loss of the fabricated device including a 90◦ hybrid and a 3-{dB} coupler is {\textless}1 {dB} in a bandwidth over 80 nm. Our analysis also shows large fabrication tolerance with width of ±0.1 μm or length of ±3 μm.},

abstract = {We demonstrate the first simplified coherent receiver using a 120\&\#x000B0; hybrid on silicon-on-insulator ({SOI}) for high speed {PON} applications. This coherent receiver integrates an inverse taper edge coupler for the received signal, a vertical grating coupler for the local oscillator input, a polarization splitter and rotator ({PSR}), a 120\&\#x000B0; hybrid based on a 3\&\#x000D7;3 multimode interference ({MMI}) coupler, and three germanium photodetectors. We achieved 25 Gbit/s two-level pulse amplitude modulation ({PAM}-2) transmission over 30 km standard single mode fiber ({SMF}) in the C-band without any digital signal processing ({DSP}) (e.g., pre-emphasis, pulse shaping, equalization, nonlinearity compensation) and dispersion compensation (e.g., optical or digital) either at the transmitter or at the receiver. The requirements for frequency and phase locking of the local oscillator ({LO}) were avoided due to the use of intensity modulated signals. Receiver sensitivities of \&\#x02212;23.70 {dBm}, \&\#x02212;20.30 {dBm}, and \&\#x02212;15.10 {dBm} are achieved at a bit error rate ({BER}) below the hard-decision forward error correction ({HD}-{FEC}) threshold (i.e., 3.8 \&\#x000D7; 10\&\#x02212;3) in back-to-back (B2B), after 21 km and 30 km, respectively. We also demonstrate 25 Gbit/s {PAM}-4 transmission achieving receiver sensitivities of \&\#x02212;15.30 {dBm}, \&\#x02212;13.90 {dBm}, and \&\#x02212;9.50 {dBm} below the {HD}-{FEC} threshold in B2B, after 10.5 km and 21 km, respectively.},

abstract = {A coherent receiver based on a 120° downconverter architecture, inherited from previous approaches at the microwave and optical fields, is proposed, analyzed, numerically evaluated and compared to the conventional 90° downconverter alternative. It is shown that, due to its superior calibration procedure, the new downconverter architecture allows full compensation of the imbalances in its optical front-end thus leading to an extended dynamic range and a broader operating bandwidth than its 90° counterpart. Simulation results from monolithically integrated downconverters show that our approach can be an interesting alternative to support efficient modulation schemes such as M-{QAM} that is being studied as potential candidate for the next generation of optical communication systems.},

abstract = {A general-purpose photonic processor can be built integrating a silicon photonic programmable core in a technology stack comprising an electronic monitoring and controlling layer and a software layer for resource control and programming. This processor can leverage the unique properties of photonics in terms of ultra-high bandwidth, high-speed operation, and low power consumption while operating in a complementary and synergistic way with electronic processors. These features are key in applications such as next-generation 5/6 G wireless systems where reconfigurable filtering, frequency conversion, arbitrary waveform generation, and beamforming are currently provided by microwave photonic subsystems that cannot be scaled down. Here we report the first general-purpose programmable processor with the remarkable capability to implement all the required basic functionalities of a microwave photonic system by suitable programming of its resources. The processor is fabricated in silicon photonics and incorporates the full photonic/electronic and software stack.},

abstract = {A highly flexible, stacked, switch module is proposed, wherein multiple independent 1 × N wavelength selective switches ({WSSs}) can be realized on a single 4k liquid crystal on silicon device. The stacked {WSS} module can be configured in different ways for application at either the transit side or the add/drop side of a colorless, directionless, and contentionless ({CDC}) reconfigurable optical add/drop multiplexer ({ROADM}). Two {ROADM} architectures are proposed based on the stacked {WSS} modules. Their costs are analyzed for both a 4-deg network node and a larger 8-deg node. The first proposed {ROADM} architecture with full {CDC} features is shown to realize a cost reduction of at least 35\% in these two test network nodes, when compared with the conventional {CDC} {ROADM} architecture based on the standalone {WSSs} and multicasting switches ({MCSs}). The second {ROADM} architecture proposed has a small probability of wavelength contention, which could be prevented by a local wavelength assignment algorithm. According to our cost estimation, we are able to aggressively reduce the number of components at the add/drop side and make an overall cost reduction of {\textgreater}70\% and {\textgreater}80\% in the 4- and 8-deg network nodes, respectively.},

These interferometers are typically composed of a regular mesh of beam splitters and phase shifters, allowing for straightforward fabrication using integrated photonic architectures and ready scalability. The current, standard design for universal multiport interferometers is based on work by Reck et al (Phys. Rev. Lett. 73, 58, 1994). We demonstrate a new design for universal multiport interferometers based on an alternative arrangement of beam splitters and phase shifters, which outperforms that by Reck et al.

abstract = {Programmable Integrated Photonics is a recent area of research that aims to integrate a very-large scale of reconfigurable photonic components to enable flexible and versatile photonic integrated circuits. In this paper, we review the state of the art of general-purpose waveguide mesh arrangements with a special focus on those that allow the synthesis of optical feedback loops. Moreover, we propose for the first time, a new design approach to generate waveguide mesh patterns with equally-oriented components. This innovation is of special relevance to improve performance and to mitigate one of the main scalability limitations, the integration density. The paper finalizes with an introduction to control algorithms for waveguide mesh arrangements based on derivative methods and non-derivative methods. These control methods provide a proof for the self-reconfiguration of large-scale waveguide mesh arrangements. In particular, we apply the computational optimization algorithms to program a hexagonal waveguide mesh to emulate a 1 × 8 beamforming network and an optical filter based on an unbalanced {MZI} design. All in all, the paper comprises recipes to achieve truly practical software-defined photonic integrated circuits.},

Compared to the triangular (Reck) mesh, our proposed diamond mesh makes use of a larger number of {MZIs}, leading to a symmetric topology and adding additional degrees of freedom for the weight matrix optimization in the backpropagation process. Furthermore, the additional {MZIs} enable the diamond mesh to optimally eliminate the excess light intensity that degrades the performance of the {ONNs} through the tapered out waveguides. Our results show that the diamond topology is more robust to the inevitable imperfections in practice, i.e., insertion loss of the constituent {MZIs} and the phase errors. This robustness allows for better classification accuracy in the presence of experimental imperfections. The practical performance and the scalability of the two structures implementing different sizes of optical neural networks are analytically compared. The obtained results confirm that the diamond mesh is more error-and loss-tolerant in classifying the data samples in different sizes of {ONNs}.},

abstract = {Artificial neural networks are computational network models inspired by signal processing in the brain. These models have dramatically improved performance for many machine-learning tasks, including speech and image recognition. However, today's computing hardware is inefficient at implementing neural networks, in large part because much of it was designed for von Neumann computing schemes. Significant effort has been made towards developing electronic architectures tuned to implement artificial neural networks that exhibit improved computational speed and accuracy. Here, we propose a new architecture for a fully optical neural network that, in principle, could offer an enhancement in computational speed and power efficiency over state-of-the-art electronics for conventional inference tasks. We experimentally demonstrate the essential part of the concept using a programmable nanophotonic processor featuring a cascaded array of 56 programmable Mach-Zehnder interferometers in a silicon photonic integrated circuit and show its utility for vowel recognition.},

abstract = {In this paper, a coherent multiple-input multiple-output ({MIMO}) radar system with widely separated antennas is simulated in three-dimensional (3D) surveillance scenarios. This analysis proceeds in parallel with the design and development of a system demonstrator based on photonic technology. Microwave photonics permits to conceive an architecture where all radar signals are coherently generated and received in a photonics-based central unit and optically distributed/collected to/from the radar heads where antennas are located, through optical fiber links, maintaining the coherence. Albeit centralized coherent data fusion becomes possible, preliminary results show how secondary lobes represent the major limiting factor for the radar's performance. Nonetheless, diversity in the spatial and/or frequency domains become a crucial resource to circumvent this problem. A {MIMO} radar simulator is proposed to estimate the coherent ambiguity function in 3D multi-target multi-band scenarios. Preliminary simulation results, concerning 3D scenarios considered of high interest for automotive and other applications, show that coherence in {MIMO} systems allows to achieve an angular and height resolution very close to the theoretical limit given by the used {RF} wavelength and baseline length, thus confirming the huge potential of coherent {MIMO} radars in 3D applications.},

Due to random phase offsets in the {MZIs} resulting from fabrication process variations, they are initially configured through an experimental protocol. The presented calibration scheme allows to straightforwardly characterize the {MZIs} to mitigate the possible input phase errors and determine the bar and cross states of each {MZI} for tuning it at the required sate before programming the device. After the configuration process, the device can be programmed to construct the linear transformation matrix of the application. In this regard, using the required bias voltages, the phase shifts obtained from the decomposition process are applied to the phase shifters of the {MZIs} in the device.},

abstract = {With the proliferation of ultrahigh-speed mobile networks and internet-connected devices, along with the rise of artificial intelligence ({AI})1, the world is generating exponentially increasing amounts of data that need to be processed in a fast and efficient way. Highly parallelized, fast and scalable hardware is therefore becoming progressively more important2. Here we demonstrate a computationally specific integrated photonic hardware accelerator (tensor core) that is capable of operating at speeds of trillions of multiply-accumulate operations per second (1012 {MAC} operations per second or tera-{MACs} per second). The tensor core can be considered as the optical analogue of an application-specific integrated circuit ({ASIC}). It achieves parallelized photonic in-memory computing using phase-change-material memory arrays and photonic chip-based optical frequency combs (soliton microcombs3). The computation is reduced to measuring the optical transmission of reconfigurable and non-resonant passive components and can operate at a bandwidth exceeding 14 gigahertz, limited only by the speed of the modulators and photodetectors. Given recent advances in hybrid integration of soliton microcombs at microwave line rates3–5, ultralow-loss silicon nitride waveguides6,7, and high-speed on-chip detectors and modulators, our approach provides a path towards full complementary metal–oxide–semiconductor ({CMOS}) wafer-scale integration of the photonic tensor core. Although we focus on convolutional processing, more generally our results indicate the potential of integrated photonics for parallel, fast, and efficient computational hardware in data-heavy {AI} applications such as autonomous driving, live video processing, and next-generation cloud computing services. An integrated photonic processor, based on phase-change-material memory arrays and chip-based optical frequency combs, which can operate at speeds of trillions of multiply-accumulate ({MAC}) operations per second, is demonstrated.},

abstract = {Photonic spiking neural networks ({PSNNs}) potentially offer exceptionally high throughput and energy efficiency compared to their electronic neuromorphic counterparts while maintaining their benefits in terms of event-driven computing capability. While state-of-the-art {PSNN} designs require a continuous laser pump, this paper presents a monolithic optoelectronic {PSNN} hardware design consisting of an {MZI} mesh incoherent network and event-driven laser spiking neurons. We designed, prototyped, and experimentally demonstrated this event-driven neuron inspired by the Izhikevich model incorporating both excitatory and inhibitory optical spiking inputs and producing optical spiking outputs accordingly. The optoelectronic neurons consist of two photodetectors for excitatory and inhibitory optical spiking inputs, electrical transistors\&\#x2019; circuits providing spiking nonlinearity, and a laser for optical spiking outputs. Additional inclusion of capacitors and resistors complete the Izhikevich-inspired optoelectronic neurons, which receive excitatory and inhibitory optical spikes as inputs from other optoelectronic neurons. We developed a detailed optoelectronic neuron model in Verilog-A and simulated the circuit-level operation of various cases with excitatory input and inhibitory input signals. The experimental results closely resemble the simulated results and demonstrate how the excitatory inputs trigger the optical spiking outputs while the inhibitory inputs suppress the outputs. The nanoscale neuron designed in our monolithic {PSNN} utilizes quantum impedance conversion. It shows that estimated 21.09 {fJ}/spike input can trigger the output from on-chip nanolasers running at a maximum of 10 Gspike/second in the neural network. Utilizing the simulated neuron model, we conducted simulations on {MNIST} handwritten digits recognition using fully connected ({FC}) and convolutional neural networks ({CNN}). The simulation results show 90\&\#x0025; accuracy on unsupervised learning and 97\&\#x0025; accuracy on a supervised modified {FC} neural network. The benchmark shows our {PSNN} can achieve 50 {TOP}/J energy efficiency, which corresponds to 100\&\#x2009;\&\#x00D7;\&\#x2009;throughputs and 1000\&\#x2009;\&\#x00D7;\&\#x2009;energy-efficiency improvements compared to state-of-art electrical neuromorphic hardware such as Loihi and {NeuroGrid}.},

abstract = {We show how to design an optical device that can perform any linear function or coupling between inputs and outputs. This design method is progressive, requiring no global optimization. We also show how the device can configure itself progressively, avoiding design calculations and allowing the device to stabilize itself against drifts in component properties and to continually adjust itself to changing conditions. This self-configuration operates by training with the desired pairs of orthogonal input and output functions, using sets of detectors and local feedback loops to set individual optical elements within the device, with no global feedback or multiparameter optimization required. Simple mappings, such as spatial mode conversions and polarization control, can be implemented using standard planar integrated optics. In the spirit of a universal machine, we show that other linear operations, including frequency and time mappings, as well as nonreciprocal operation, are possible in principle, even if very challenging in practice, thus proving there is at least one constructive design for any conceivable linear optical component; such a universal device can also be self-configuring. This approach is general for linear waves, and could be applied to microwaves, acoustics, and quantum mechanical superpositions.},

abstract = {Growing interest in quantum computing for practical applications has led to a surge in the availability of programmable machines for executing quantum algorithms1,2. Present-day photonic quantum computers3–7 have been limited either to non-deterministic operation, low photon numbers and rates, or fixed random gate sequences. Here we introduce a full-stack hardware−software system for executing many-photon quantum circuit operations using integrated nanophotonics: a programmable chip, operating at room temperature and interfaced with a fully automated control system. The system enables remote users to execute quantum algorithms that require up to eight modes of strongly squeezed vacuum initialized as two-mode squeezed states in single temporal modes, a fully general and programmable four-mode interferometer, and photon number-resolving readout on all outputs. Detection of multi-photon events with photon numbers and rates exceeding any previous programmable quantum optical demonstration is made possible by strong squeezing and high sampling rates. We verify the non-classicality of the device output, and use the platform to carry out proof-of-principle demonstrations of three quantum algorithms: Gaussian boson sampling, molecular vibronic spectra and graph similarity8. These demonstrations validate the platform as a launchpad for scaling photonic technologies for quantum information processing.},

This advantage stems from the inherent suitability of optical signals to carry out matrix multiplication. However, even deterministic phenomena such as thermal crosstalk make precise programming of photonic chips a challenging task. Here, we train and experimentally evaluate three models incorporating varying degrees of physics intuition to predict the effect of thermal crosstalk in different locations of an integrated programmable photonic mesh. We quantify the effect of thermal crosstalk by the resonance wavelength shift in the power spectrum of a microring resonator implemented in the chip, achieving modelling errors {\textless} 0.5 pm. We experimentally validate the models through compensation of the crosstalk-induced wavelength shift. Finally, we evaluate the generalization capabilities of one of the models by employing it to predict and compensate for the effect of thermal crosstalk for parts of the chip it was not trained on, revealing root-mean-square-errors of {\textless} 2.0 pm.},

Traditional experimental implementations need N2 units such as Mach-Zehnder interferometers ({MZIs}) for an input dimension N to realize typical computing operations (convolutions and matrix multiplication), resulting in limited scalability and consuming excessive power. Here, we propose the integrated diffractive optical network for implementing parallel Fourier transforms, convolution operations and application-specific optical computing using two ultracompact diffractive cells (Fourier transform operation) and only N {MZIs}. The footprint and energy consumption scales linearly with the input data dimension, instead of the quadratic scaling in the traditional {ONN} framework. A {\textasciitilde}10-fold reduction in both footprint and energy consumption, as well as equal high accuracy with previous {MZI}-based {ONNs} was experimentally achieved for computations performed on the {MNIST} and Fashion-{MNIST} datasets.

Diffractive networks, in particular, bring deep-learning principles into the design and operation of free-space optical systems to create new functionalities. Metasurfaces consisting of deeply subwavelength units are achieving exotic optical responses that provide independent control over different properties of light and can bring major advances in computational throughput and data-transfer bandwidth of free-space optical processors. Unlike integrated photonics-based optoelectronic systems that demand preprocessed inputs, free-space optical processors have direct access to all the optical degrees of freedom that carry information about an input scene/object without needing digital recovery or preprocessing of information. To realize the full potential of free-space optical computing architectures, diffractive surfaces and metasurfaces need to advance symbiotically and co-evolve in their designs, 3D fabrication/integration, cascadability, and computing accuracy to serve the needs of next-generation machine vision, computational imaging, mathematical computing, and telecommunication technologies.},

abstract = {Most modern computing tasks have digital electronic input and output data. Due to these constraints imposed by real-world use cases of computer systems, any analog computing accelerator, whether analog electronic or optical, must perform an analog-to-digital conversion on its input data and a subsequent digital-to-analog conversion on its output data. The energy and latency costs incurred by data conversion place performance limits on analog computing accelerators. To avoid this overhead, analog hardware must replace the full functionality of traditional digital electronic computer hardware. This is not currently possible for optical computing accelerators due to limitations in gain, input-output isolation, and information storage in optical hardware. This article presents a case study that profiles 27 benchmarks for an analog optical Fourier transform and convolution accelerator which we designed and built. The case study shows that an ideal optical Fourier transform and convolution accelerator can produce an average speedup of 9.4× and a median speedup of 1.9× for the set of benchmarks. The optical Fourier transform and convolution accelerator only produces significant speedup for pure Fourier transform (45.3×) and convolution (159.4×) applications.},

While other textbooks concentrate only on language features, Circuit Design with {VHDL} offers a fully integrated presentation of {VHDL} and design concepts by including a large number of complete design examples, illustrative circuit diagrams, a review of fundamental design concepts, fully explained solutions and simulation results. The text presents the information concisely yet completely, discussing in detail all indispensable features of the {VHDL} synthesis. The book is organised in a clear progression, with the first part covering the circuit level, treating foundations of {VHDL} and fundamental coding, and the second part covering the system level (units that might be located in a library for code sharing, reuse and partitioning), expanding upon the earlier chapters to discuss system coding. techniques of {VHDL}, including code structure, data types, operators and attributes, concurrent and sequential statements and code, objects (signals, variables and constants), design of finite state machines and examples of additional circuit designs. Part {II}, System Design, builds on the material already presented, adding elements intended mainly for library allocation; it examines packages and components, functions and procedures and additional examples of system design. Appendixes on programmable logic devices ({PLDs}/{FPGAs}) and synthesis tools follow Part {II}. The book's highly original approach of teaching through extensive system examples as well as its unique integration of {VHDL} and design make it suitable both for use by students in computer science and electrical engineering.},

abstract = {The algorithm described in this paper is the outcome of an endeavor to answer the following question: Is it possible to find procedures which would enable a computer to solve efficiently path-connection problems inherent in logical drawing, wiring diagramming, and optimal route finding? The results are highly encouraging. Within our framework, we are able to solve the following types of problems: 1) To find a path between two points so that it crosses the least number of existing paths. 2) To find a path between two points so that it avoids as much as possible preset obstacles such as edges. 3) To find a path between two points so that the path is optimal with respect to several properties; for example, a path which is not only one of those which cross the fewest number of existing paths, but, among these, is also one of the shortest. The minimal-distance solution has been programmed on an {IBM} 704 computer, and a number of illustrations are presented. The class of problems solvable by our algorithm is given in a theorem in Section {III}. A byproduct of this algorithm is a somewhat remote, but unexpected, relation to physical optics. This is discussed in Section {VI}.},

abstract = {This book provides the first comprehensive, up-to-date and self-contained introduction to the emergent field of Programmable Integrated Photonics ({PIP}). It covers both theoretical and practical aspects, ranging from basic technologies and the building of photonic component blocks, to design alternatives and principles of complex programmable photonic circuits, their limiting factors, techniques for characterization and performance monitoring/control, and their salient applications both in the classical as well as in the quantum information fields. The book concentrates and focuses mainly on the distinctive features of programmable photonics, as compared to more traditional {ASPIC} approaches. After some years during which the Application Specific Photonic Integrated Circuit ({ASPIC}) paradigm completely dominated the field of integrated optics, there has been an increasing interest in {PIP}. The rising interest in {PIP} is justified by the surge in a number of emerging applications that call for true flexibility and reconfigurability, as well as low-cost, compact, and low-power consuming devices. Programmable Integrated Photonics is a new paradigm that aims at designing common integrated optical hardware configurations, which by suitable programming, can implement a variety of functionalities. These in turn can be exploited as basic operations in many application fields. Programmability enables, by means of external control signals, both chip reconfiguration for multifunction operation, as well as chip stabilization against non-ideal operations due to fluctuations in environmental conditions and fabrication errors. Programming also allows for the activation of parts of the chip, which are not essential for the implementation of a given functionality, but can be of help in reducing noise levels through the diversion of undesired reflections.},

abstract = {Reconfigurable photonic filters show great promise as a potential solution to meet the evolving needs of future microwave communication systems. By integrating high-performance filters into programmable microwave photonic processors, they can provide significant benefits for signal processing applications. The development of an algorithm that can automatically characterize and reconfigure the filter using a single optical input and output port is essential for this purpose. This paper presents an optimization technique for a fully tunable ring-assisted Mach–Zehnder interferometer filter. The proposed filter design eliminates the need for monitoring components and employs a novel algorithm that operates independently in each ring by switching between the two arms of the filter. In addition, the filter can be configured to implement different filter architectures, allowing for flexible filtering requirements. Measurements were performed using the device as an interleaver, implementing different types of infinite impulse response filters in the optical and radio frequency domains. Side-coupled integrated spaced sequence of resonator filters were also implemented by reconfiguring the same device. These results demonstrate the exceptional reconfigurability of the filter design proposed herein in terms of bandwidth and central frequency.},

abstract = {The significant advancements in integrated photonics have enabled high-speed and energy efficient systems for various applications from data communications and high-performance computing, to medical diagnosis, sensing and ranging. However, data storage in these systems has been dominated by electronic memories which necessitates signal conversion between optical and electrical as well as analog and digital domains, and data movement between processor and memory that reduce the speed and energy efficiency. To date, a scalable optical memory with optical control has remained an open problem. Here we report an integrated photonic set-reset latch as a fundamental optical static memory unit based on universal optical logic gates. While the proposed memory is compatible with different photonic platforms, its functionality is demonstrated on a programmable silicon photonic chip as a proof of concept. Optical set, reset, and complementary outputs, scalability to a large number of memory units via the independent latch supply light, and compatibility with different photonic platforms enable more efficient and lower latency optical processing systems.},
