This compilation of review articles by leading experts presents clearly the trend in future optoelectronic devices. It is clear that optoelectronic and photonic integration help to further improve high-speed system capabilities and increase the total systems and network capacities with WDM technology. The foundation of the integration technology is based on quantum well materials, and advanced epitaxial growth and device processing techniques. The integrated laser/ modulators, multi-wavelength laser arrays, and OEIC receivers have demonstrated the feasibility of this technology, but much work remains to be done to put such technology to practice.

Our intent in producing this book was to provide a text that would be comprehensive enough for an introductory course in integrated optics, yet concise enough in its mathematical derivations to be easily readable by a practicing engineer who desires an overview of the field. The response to the first edition has indeed been gratifying; unusually strong demand has caused it to be sold out during the initial year of publication, thus providing us with an early opportunity to produce this updated and improved second edition. This development is fortunate, because integrated optics is a very rapidly progressing field, with significant new research being regularly reported. Hence, a new chapter (Chap. 17) has been added to review recent progress and to provide numerous additional references to the relevant technical literature. Also, thirty-five new problems for practice have been included to supplement those at the ends of chapters in the first edition. Chapters I through 16 are essentially unchanged, except for brief updating revisions and corrections of typographical errors. Because of the time limitations imposed by the need to provide an uninterrupted supply of this book to those using it as a course text, it has been possible to include new references and to briefly describe recent developments only in Chapter 17. However, we hope to provide details of this continuing progress in a future edition.

In this fifth edition all chapters have been revised and updated. The chapters on Polymer and Fiber Integrated Optics, Optical Amplifiers, Micro-Optical-Electro-Mechanical Devices, and Photonic and Microwave Wireless Systems are completely new. Problems help the students to deepen their knowledge.

In the last decade, China has experienced one of the fastest economic growth in the world. Leading this enormous growth is the development of telecommunications that has a growth rate far exceeding that of its GNP. With such fast growth, China will have the largest telecommunication network with 420 million lines by 2010. The backbone of the national telecom network in China is primarily optical fiber cables today.This book contains a selection of reports reviewing the progress of the research and development in optoelectronics and optical fiber communications in China. The first four papers focus on the current development in optical fiber communications with particular interest in studies of soliton transmission and optical WDM transmission experiments. The next four papers describe the research results on quantum well lasers, bi-stable lasers, electro-absorption modulators and SEED, and photonic integrated devices. Fiber ring lasers using EDFA and the ASE noise in the PIN receiver due to EDFA are discussed in the next two papers, respectively. The last two papers describe the research activities and results of the development of the GaAs ICs for high speed lighwave systems, and their characterization using optical sampling techniques. The contents included in this book may be regarded as the epitome of the current status of research in this field in mainland China.

This book is an introduction to the theory and technology of integrated op tics for graduate students in electrical engineering, and for practicing engi neers and scientists who wish to improve their understanding of the princi pIesand applications ofthis relatively new, and rapidly growing, field. Integrated Optics is the name given to a new generation of opto-electro nie systems in which the familiar wires and cables are replaced by light waveguiding optical fibers, and conventional integrated circuits are replaced by optical integrated circuits (OIC's). In an OIC, the signal is carried by means of a beam of light rather than by an electrical current, and the various circuit elements are interconnected on the substrate wafer by optical wave guides. Some advantages of an integrated-optic system are reduced weight, increased bandwidth (or multiplexing capability), resistance to electro magnetic interference, and low loss signal transmission. Because of the voluminous work that has been done in the field of inte grated optics since its inception in the late 1960's, the areas of fiber optics and optical integrated circuits have usually been treated separately at confe rences and in textbooks. In the author's opinion, this separation is unfortu nate because the two areas are closely related. Nevertheless, it cannot be denied that it may be a practical necessity.

This book covers the principles, methodology, and prototypes of sensing skin-like devices and related intelligence and software. Sensitive Skins are large-area and flexible arrays of sensors integrated onto the entire surface of machines. Sensitive Skin will endow these machines with the senses of proximity, touch, pressure, temperature, and chemical/biological agents, thus making possible the use of unsupervised machines in unstructured and unpredictable surroundings. Sensitive Skin will make machines “cautious” and thus friendly to their environment. It will revolutionize service industries, make important contributions to human prosthetics, and augment human sensing when fashioned into clothing. Being transducers producing massive data flow, Sensitive Skin devices will constitute yet another advance in the information revolution.

Professor Hunsperger's Integrated Optics is one of the few texts that is comprehensive and thorough enough for use both as a classroom text (practice problems are included) and as a specialist's reference. The gratifying success of the first two editions and the continuing rapid development of the field necessitated the writing of this third edition. All chapters have been revised and updated, and a new chapter, on quantum well devices, has been added. As in the previous editions, detailed descriptions of the phenomena, devices, and technology used in optical integrated circuits and their relationship to fiber optics are presented. The trend of telecommunications toward the use of single mode systems operating at the longer wavelengths of 1.3 and 1.55 μm is explained and documented with illustrations of recently developed devices and systems. Broader coverage of GaInAsP devices and optical integrated circuits is provided, and the new growth tech- niques of molecular beam epitaxy (MBE) and metal-organic chemical vapor deposition (MOCVD) are described. A discussion of the extensive development of hybrid optical integrated circuits in lithium niobate is also included. From the reviews: I never had the opportunity of using Hunsperger as a text to teach from but after reading the present third edition, I think it must be a pleasure to do so. It is a good book because of its precise language and its didactic organization (with many clear tables), it is exhaustive in its details, and rigorous in its background; it is well suited for a graduate-level course.

Surface acoustic wave (SAW) devices are recognized for their versatility and efficiency in controlling and processing electrical signals. This has resulted in a multitude of device concepts for a wide range of signal processing functions, such as delay lines, filters, resonators, pulse compressors, convolvers, and many more. As SAW technology has found its way into mass market products such as TV receivers, pagers, keyless entry systems and cellular phones, the production volume has risen to millions of devices produced every day. At the other end of the scale, there are specialized high performance signal processing SAW devices for satellite communication and military applications, such as radar and electronic warfare. This volume, together with Volume 2, presents an overview of recent advances in SAW technology, systems and applications by some of the foremost researchers in this exciting field.

The rapid pace of the electronic technology evolution compels a merger of technical areas such as low-power digital electronics, microwave power circuits, optoelectronics, etc., which collectively have become the foundation of today's electronic technology. The 1999 Workshop on Frontiers in Electronics gathered experts from academia, industry, and government agencies to review the recent exciting breakthroughs and their underlying physical mechanisms. The proceedings addresses controversial issues, provocative views, and visionary outlooks. Also included are discussions on the future trends, the directions of electronics technology and the market pulls, as well as the necessary policy and infrastructure changes.
