The material presented in this volume is based on a series of lectures presented at an annual short course entitled "e;Integrated Optics"e; 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 "e;Integrated Optics."e; 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.
