A survey of products and research projects in the field of highly parallel, optical and neural computers in Japan. The research activities are listed by type of organization, eg universities and public research organizations, and by industry.
Forty seven contributions discuss broad concepts, systems and architectures, devices, and materials, offering both a cross-section and a complete image of current research. Every aspect of this technology of the (rapidly approaching) future is under study by the Japanese, and this volume provides ac
Some of the most ingenious and attractive modern motifs. 746 designs.
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.
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.
The perspectives of technologists, economists, and policymakers are brought together in this volume. It includes chapters dealing with approaches to assessment of technology leadership in the United States and Japan, an evaluation of future impacts of eroding U.S. technological preeminence, an analysis of the changing nature of technology-based global competition, and a discussion of policy options for the United States.
