In 1945, Dr. Ernst Weber founded, and was the first Director of, the Microwave Research Institute (MRI) at Polytechnic University (at that time named the Polytechnic Institute of Brooklyn). MRI gained worldwide recognition in the 50s and 60s for its research in electromagnetic theory, antennas and radiation, network theory and microwave networks, microwave components, and devices. It was also known through its series of 24 topical symposia and the widely distributed hardbound MRI Symposium Proceedings. Rededicated as the Weber Research Institute (WRI) in 1986, the institute currently conducts research in such areas as electromagnetic propagation and antennas, ultrabroadband electromagnetics, pulse power, acoustics, gaseous electronics, plasma physics, solid-state materials, quantum electronics, electromagnetic launchers, and networks. Following MRI tradition, WRI has launched its own series of in-depth topical conferences with published proceedings. Previous conferences in this series were: Directions in Electromagnetic Wave Modeling; October 1990 Ultra-Wideband Short-Pulse Electromagnetics; October, 1992 Ultra-Wideband Short-Pulse Electromagnetics, II; October, 1994 The proceedings of these conferences were also published by Plenum Press. This volume constitutes the proceedings of the fourth WRI International Conference dealing with Guided-Wave Optoelectronics: Device Characterization, Analysis and Design. The conference was held October 26-28, 1994, at the Polytechnic University in Brooklyn, New York, in cooperation with the IEEE Lasers and Electro Optics Society, and with the Optical Society of America.

Griffel Photonics in telecommunications. ... ... ... ... 3 ... ... H The book is a completely new survey of the most recent advances in the areas of integrated optics and optelectronics. Written by nine authors who are internationally recognized authorities in their areas, the book contains chapters on optical waveguides, lightwave junctions and other thin-film components, lithium-niobate (LiNbO3) devices, guided-mode semiconductor (GaAs and related) lasers and integrated optic devices. Included are sections on basic theory as well as detailed descriptions of fabrication technology, applications and a plethora of available devices. The book should be of great interest to all researchers and engineers involved with integrated optics, optoelectronics and electro-optic systems and devices. Because of the systematic arrangement of its chapters, the book should also be very useful to graduate and senior undergraduate students. In addition, it will serve as a comprehensive reference manual for the theory and application of the most recent thin-film optical and optoelectronic technology.
