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.

Computers, telecommunications equipment, semiconductors - the products and technologies of the information and communications (IC) industry have transformed our world. Most of these products were initially developed in Western countries, but by the early 1990s some of the world's largest companies in the field were Japanese. This book explains the resurgence of Japan's IC giants, their global status, and their strengths and weaknesses. Empirical scrutiny of their evolution is the author'sown theory of the most appropriate method for studying the dynamics of long-term industrial change. While the Japanese motor vehicle and consumer electronics industries have been relatively well analysed, there are no comprehensive up-to-date studies of the Japanese IC industry. This book addresses the questions consequently left unanswered: How were Japanese IC companies able to catch up with their western rivals--and in some cases overtake them? How have Japanese IC companies responded to the post-IBM world of computing? Why do they remain primarily dependent on the Japanese market? Why do they combine competences in computers, semiconductors, and telecommunications equipment, while their US counterparts are far more specialized? What role has been played by the Japanese government and the system of controlled competition in their success? Will Japanese IC companies become increasingly competitive internationally in the future? The author extends the evolutionary approach to the organization of the firm and industry developed by such writers as Schumpeter, Nelson, Winter, and Chandler. He argues that in order to understand the evolution of companies and industries, it is necessary to create a theory of the firm capable of encompassing the development of real firms in the real world in real time. This approach stresses the importance of the beliefs that are constructed in the firm under conditions of 'interpretive ambiguity', which guide the firm's decisions and its reactions to new technologies. Lengthy analyses of NEC and NTT (by far the world's largest company in terms of market value; its future currently under government scrutiny), and of the computing, switiching, and optical fibre industries, illustrate these concepts. Based on over 600 personal interviews over eight years with Japanese leaders, this book provides important new material on the past, present, and future of Japanese industry.

International Trends in Optics provides a broad view of work in the field of optics throughout the world. Topics range from quantum optoelectronics for optical processing to optics in telecommunications, along with microoptics, optical memories, and fiber-optic signal processing. Holographic optical elements for use with semiconductor lasers are also considered. Comprised of 34 chapters, this book begins with an introduction to some of the practical applications of integrated optical circuits, optoelectronic integrated circuits, and photonic integrated circuits. Subsequent chapters deal with quantum optoelectronics for optical processing; fiber-optic signal processing; holographic optical elements for use with semiconductor lasers; potential uses of photorefractives; and adaptive interferometry that makes use of photorefractive crystals. Water wave optics and diffraction are also examined, together with the essential journals of optics and the opposition effect in volume and surface scattering. The final chapter is devoted to optical computing, with emphasis on its processing functions and architecture. This monograph will be of interest to students, practitioners, and researchers in physics and electronics.

"Techno-globalism" is the term used by policymakers to describe the process of opening government and Research and Development programs to foreign participation. This book focuses on Japan's approach to techno-globalism, in particular the policies of the Ministry of International Trade and Industry (MITI). It also explores the politics underlying the approach to this issue in the triad of leading R&D centers - Japan, the United States, and the European Union. The author examines various theoretical approaches to the political economy of globalization, and he describes systems of innovation in Japan, the United States, and the European Union, emphasizing research linkages among forms, national labs, and universities.

This volume surveys the entire field of optical computing. The emphasis is on breadth of coverage. The book is descriptive, the authors minimize the use of mathematics, and it is therefore most suitable for those who require an overall view of what is going on in this field. A detailed comparison is given of the capabilities of electronics and optics, and the degree to which these capabilities have been achieved is indicated. Other areas of focus include optical computing architectures, components and technologies, optical interconnects, and optical neural nets. Approximately 300 references to key works in the field are included.
