Integrated Optics: Theory and Technology provides a comprehensive and thorough treatment suitable for use both as a classroom text (practice problems are included) and as a specialist's reference. Detailed descriptions of the phenomena, devices, and technology used in optical integrated circuits and their relationship to fiber optics are presented. In this fourth edition all chapters have been completely revised.

This volume contains the proceedings of a two-week NATO A.S.I. on Integrated Optics: Physics and Applications, held from August 17 to August 30, 1981 in Erice, Italy. This is the 8th annual Course of the "International School of Quantum Electronics" presented under the auspices of the "E. Majorana" Centre for Scientific Culture. The subject was chosen in order to satisfy the demand for a course on integrated optics which is relevant to the expanding use of fiber optics for communication and signal processing. Integrated Optics, encompassing all of the optical waveguide circuits which are the optical analog of integrated circuits, is finding its way into a variety of applications involving communi cations, high speed signal-processing, and sensors of many kinds. However, because the technology is still changing very rapidly, the development of these exciting applications relies heavily upon the physics of the integrated optical circuits themselves and the pro cessing techniques used to fabricate them. This NATO A.S.I. provided not only a thorough tutorial treatment of the field, but also through panel discussions and additional lectures treated topics at the forefront of present work. Therefore the character of the Course was a blend of current research and tutorial reviews. "The Physics and Applications of Integrated Optics" could hardly be a more appropriate title to be chosen for this volume. Many of the worlds' acknowledged leaders in the field have been brought together to review and speculate on the accomplishments of integrated optics.

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.

Controlling the mechanical, electrical, magnetic, and optical properties of materials by advanced fabrication methods (Le. ; Molecular Beam Epitaxy and Metal-Organic Chemical Vapor Deposition) has become the new paradigm in our research era. Sensors, being the most vital part of the electronic data processing and decision making machines, stand to gain the most from engineering of the properties of materials. Microfabrication technology has already contributed significantly to the batch fabrication of micro-sensors with higher over all qualities compared to their counterparts that are fabricated using other methods. Batch fabrication of micro-sensors i) results in more uniform properties of co-fabricated devices, ii) nearly eliminates the need for characterization of individual sensors, and iii) eliminates a need for laborious alignment procedures. A less obvious benefit of using microfabrication methods is the possibility of precise control over the dimensions of the sensor. This control enables engineering of some of the properties of the material which affect the sensor's operation. There are many examples of this in the literature. Optical sensors are known to have superior properties over their counterparts that use other (i. e. ; electrostatic and magnetic) means of detection. To name a few, these advantages are: i) immunity to electromagnetic interferences, ii) higher sensitivities compared to the other types of sensors, iii) simplicity of operation principles, and iv) simplicity of overall construction.

The material presented in this volume is based on a series of lectures presented at an annual short course entitled "Integrated Optics" sponsored by the University of Cali fornia, Santa Barbara, in March of 1973. Each chapter has been authored by the individual lecturing on the particular subject matter con tained in that chapter. The primary intent of this book is to pro vide the students with a written version of the lecture material. The text treats a large variety of the basic structures and analysis techniques currently being employed in the rapidly growing area of technology termed "Integrated Optics." The volume contains both material that has previously been published in scientific journals and material which has not been published elsewhere. Since the field of integrated optics is in a stage of rapid expansion, a complete coverage of all the experimental results is difficult. As a result the emphasis is placed on the funda mental theoretical ideas and experimental results. The editor gratefully acknowledges the con tributing authors and the institutions with which they are associated for their wholehearted cooperation in the preparation of this book. Particular thanks are extended to the Hughes Research Laboratories, a division of the Hughes Aircraft Company.

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.

Photons are an attractive option for testing fundamental quantum physics and developing new quantum-enhanced technology, including highly advanced computers and simulators, as well as precision sensing beyond shot-noise. Traditionally, bulk optical components have been bolted onto optical benches to realize metre-scale quantum circuits. However this approach is ultimately proving unwieldy for increasing the complexity and for scaling up to practical quantum technologies based on photons. The work presented here demonstrates a series of quantum photonic devices based on waveguide circuits embedded in miniature monolithic chips. This represents a paradigm shift in the underlying architecture of quantum optics and provides key building blocks for all-optical and hybrid quantum technologies.

The book addresses many problems of ion exchange processes in LiNbO3, LiTaO3 and KTiOPO4 ferroelectrics and II-VI semiconductor single crystals for integrated optics applications. The authors start with the fundamentals of ion exchange processes in solids (Chapter 1). Chapter 1 can be considered also as an enlarged introduction to the book. Starting with Chapter 2, the general properties of LiNbO3 and LiTaO3 crystals, the methods used to study optical waveguides in these crystals as well as advanced preparation methods of optical waveguides are reviewed. Chapters 3, 4 and 5 are devoted to recent progress in the ion exchange processes in LiNbO3, LiTaO3 and KTiOPO4 crystals, respectively, and Chapter 6 summarizes the main applications of ion-exchanged waveguides in modern integrated optics. Finally, Chapter 7 deals with recently established ion exchange processes in II-VI semiconductors.

As optical technologies move closer to the core of modern computer architecture, there arise many challenges in building optical capabilities from the network to the motherboard. Rapid advances in integrated optics technologies are making this a reality. However, no comprehensive, up-to-date reference is available to the technologies and principles underlying the field. The Encyclopedic Handbook of Integrated Optics fills this void, collecting the work of 53 leading experts into a compilation of the most important concepts, phenomena, technologies, and terms covering all related fields. This unique book consists of two types of entries: the first is a detailed, full-length description; the other, a concise overview of the topic. Additionally, the coverage can be divided into four broad areas: A survey of the basics of integrated optics, exploring theory, practical concerns, and the fundamentals behind optical devices Focused discussion on devices and components such as arrayed waveguide grating, various types of lasers, optical amplifiers, and optoelectronic devices In-depth examination of subsystems including MEMS, optical pickup, and planar lightwave circuits Finally, systems considerations such as multiplexing, demultiplexing, 3R circuits, transmission, and reception Offering a broad and complete treatment of the field, the Encyclopedic Handbook of Integrated Optics is the complete guide to the fundamentals, principles, and applications of integrated optics technology.
