Optical Computing Hardware provides information pertinent to the advances in the development of optical computing hardware. This book discusses the two application areas, namely, high-performance computing and high-throughput photonic switching. Organized into 11 chapters, this book begins with an overview of the requirements on hardware from s system perspective. This text then presents the self-electro-optic-effect devices (SPEED), the vertical-cavity-surface- emitting microlasers (VCSEL), and the vertical-to-surface transmission electrophotonic device (VSTEP). Other chapters consider the fundamental principles of the devices and their operation either as logic devices or for optical interconnection applications. This book discusses as well the planar optical microlens as an example of a refractive microlens of the gradient-index type and explains the diffractive optical elements. The final chapter describes a method for writing and reading optically in parallel from a three-dimensional matrix by means of two-photon interaction in photochromic organic materials. This book is a valuable resource for engineers, scientists, and researchers.

Optics is entering all phases of computer technology. By providing new research and ideas, it brings the reader up to date on how and why optics is likely to be used in next generation computers and at the same time explains the unique advantage optics enjoys over conventional electronics and why this trend will continue. Covered are basic optical concepts such as mathematical derivations, optical devices for optical computing, optical associative memories, optical interconnections, and optical logic. Also suggested are a number of research activities that are reinforcing the trend toward optics in computing, including neural networks, the software crisis, highly parallel computation, progress in new semiconductors, the decreasing cost of laser diodes, communication industry investments in fiber optics, and advances in optical devices. Exercises, solutions sets, and examples are provided.

As society’s appetite for information continues to grow, so does our need to process this information with increasing speed and versatility. Conventional one-size-fits-all solutions offered by digital electronics can no longer satisfy this need, as Moore’s law, interconnection density, and the von Neumann architecture reach their limits. These limitations are already being felt in advanced applications such as cognitive radio, adaptive control, and scientific computing. With its superior speed and reconfigurability, analog photonics can provide some relief to these problems; however, complex applications of analog photonics have remained largely unexplored due to the absence of a robust photonic integration industry. Recently, the landscape for commercially-manufacturable photonic chips has been changing rapidly and now promises to achieve economies of scale previously enjoyed solely by microelectronics. Despite the advent of commercially-viable photonic integration platforms, significant challenges still remain before scalable analog photonic processors can be realized. A central challenge is the development of mathematical bridges linking photonic device physics to models of complex analog information processing. Among such models, those of neural networks are perhaps the most widely studied and used by engineering communities. This book sets out to build bridges between the domains of photonic device physics and neural networks, providing a comprehensive overview of the emerging field of "neuromorphic photonics." It includes a thorough discussion of evolution of neuromorphic photonics from the advent of fiber-optic neurons to today’s state-of-the-art integrated laser neurons, which are a current focus of international research. Neuromorphic Photonics explores candidate interconnection architectures and devices for integrated neuromorphic networks, along with key functionality such as learning. It is written at a level accessible to graduate students, while also intending to serve as a comprehensive reference for experts in the field.

Optical WDM networking technology is spearheading a bandwidth revolution in the networking infrastructure being developed for the next generation Internet. Rapid advances in optical components have enabled the transition from point-to-point WDM links to all-optical networking. Optical WDM Networks: Principles and Practice presents some of the most important challenges facing the optical networking community, along with some suggested solutions. Earlier textbooks in optical networking have a narrower perspective, and rapidly advancing research has created the need for fresh and current information on problems and issues in the field. The volume editors and contributing authors have endeavoured to capture a substantial subset of the key problems and known solutions to these problems. All of the chapters are original contributions from leading international researchers. The chapters address a wide variety of topics, including the state of the art in WDM technology, physical components that make up WDM fiber-optic networks, medium access protocols, wavelength routed networks, optical access networks, network management, and performance evaluation of wavelength routing networks. The chapters also survey critical points in past research and tackle more recent problems. Practitioners and network product engineers interested in current state-of-the-art information beyond textbook-type coverage, and graduate students commencing research in this area, will appreciate the concise - and pertinent - information presented herein.

A hardware compiler for translating descriptions of digital circuits from a hardware description language (HDL) into gate-level layouts is under development at Rutgers University. The layouts are customized for optical processors that make use of arrays of optical logic gates interconnected in free-space with regular interconnection patterns such as perfect shuffles, crossovers, or global interconnects. Specific processors that the hardware compiler supports include the S-SEED based all-optical processor developed at AT & T Bell Labs, the S-SEED based all-optical processor under development at the Photonics Center at RADC/Griffiss AFB, and the acousto-optical modulator based RISC processor under development at OptiComp Corporation.
