Existing methods for nonlinear optical processing involve an intermediate photographic step which prevents real-time operation. Although optical information processors have a large space-bandwidth product, the problem of real-time input has been a major limitation in taking advantage of this processing ability. In this research, the realization of nonlinear optical processing in real time is investigated. Several techniques for performing such operations aree presented. One approach realizes the halftone method of nonlinear optical processing in real time by replacing the conventional photographic recording medium with a real-time image transducer. In the second approach halftoning is eliminated and the real-time device is used directly. In this case the nonlinearity is obtained by the inherent nonlinear characteristic of the real-time devicce. A third method uses the ability of certain real-time devices to perform an intensity-to-spatial frequency conversion.

Contemporary Nonlinear Optics discusses the different activities in the field of nonlinear optics. The book is comprised of 10 chapters. Chapter 1 presents a description of the field of nonlinear guided-wave optics. Chapter 2 surveys a new branch of nonlinear optics under the heading optical solitons. Chapter 3 reviews recent progress in the field of optical phase conjugation. Chapter 4 discusses ultrafast nonlinear optics, a field that is growing rapidly with the ability of generating and controlling femtosecond optical pulses. Chapter 5 examines a branch of nonlinear optics that may be termed nonlinear quantum optics. Chapter 6 reviews the new field of photorefractive adaptive neural networks. Chapter 7 presents a discussion of recent successes in the development of nonlinear optical media based on organic materials. Chapter 8 reviews the field of nonlinear optics in quantum confined structures. Chapter 9 reviews the field of nonlinear laser spectroscopy, with emphasis on advances made during the 1980s. Finally, Chapter 10 reviews the field of nonlinear optical dynamics by considering nonlinear optical systems that exhibit temporal, spatial, or spatio-temporal instabilities. This book is a valuable source for physicists and other scientists interested in optical systems and neural networks.

This volume contains the complete set of papers presented at the First U. S. -U. S. S. R. Sciences Cooperation Seminar on "Optical Information Processing" held at the U. S. National Academy of Sciences in Washington, D. C. from 16 - 20 June 1975 under the sponsorship of the National Science Foundation in cooperation with the U. S. S. R. Academy of Sciences. The papers present the latest theoretical advances and ex perimental state of the art in the newly developing field of "opti cal information processing", with particular emphasis on appli cations to communication, information storage and processing. Digital as well as optical systems are discussed in terms of concepts and implementations. Included are coherent and inco herent optical processing systems (for images and signals), materials and devices for optical computing, acousto-optic signal processing, memories (optical, digital and holographic), optical logic and optically-accessed digital stores, non-linear optical processing, as well as an analysis of the information capacity of optical processing systems and a report on new ex tensions of information processing in synthetic aperture radar. Detailed configurations and new manufacturing techniques for several components are presented, including such topics as "asymmetric interference fringes in reflected light" and' kino form optical elements" of very high quality; these are phase plates having a carefully controlled thickness, somewhat com parable to the famous Schmidt plates and which could have an important role in many optical computer and communications systems.

Nonlinear Optical Materials and Devices for Applications in Information Technology takes the reader from fundamental interactions of laser light in materials to the latest developments of digital optical information processing. The book emphasises nonlinear optical interactions in bulk and low-dimensional semiconductors, liquid crystals and optical fibres. After establishing the basic laser--material interactions in these materials, it goes on to assess applications in soliton propagation, integrated optics, smart pixel arrays and digital optical computing.

There has recently been a rapid growth of activity in nonlinear optics. Effects such as frequency doubling, stimulated Raman scattering, phase conjugation and solitons are of great interest both for their fundamental properties and their many important applications in science and engineering. It is mainly these applications - especially in telecommunications and information processing - that have stimulated the recent surge of activity. This book is a self contained account of the most important principles of nonlinear optics. Assuming only a familiarity with basic mathematics, the fundamentals of nonlinear optics are fully developed from basic concepts. The essential quantum mechanical apparatus is introduced and explained. In later chapters the underlying ideas are illustrated by discussing particular experimental configurations and materials. This book will be an invaluable introduction to the field for beginning graduates in physics or engineering, and will provide an excellent overview and reference work for active researchers in the field.
