Overview

This book takes a fresh look at the last three decades and enormous developments in the new electo-optic devices and associated materials. General Treatment and various proofs are at a semiquantitative level without going into detailed physics. Contains numerous worked examples and solved problems. KEY TOPICS: Chapter topics include wave nature of light, dielectric waveguides and optical fibers, semiconductor science and light emitting diodes, photodetectors, photovoltaic devices, and polarization and modulation of light. MARKET: For the study of optoelectronics by electrical engineers.
