This text surveys the most recent advances in integrated optics and optoelectronics. It contains chapters on optical waveguides, light-wave 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 descriptions of fabrication technology, applications and a number of available devices. The book will be of interest to researchers and engineers involved with integrated optics, optoelectronics and electro-optic systems and devices. In addition, it will serve as a reference manual for the theory and application of the most recent thin-film optical and optoelectronic technology. This 2nd edition contains an additional chapter summarizing the latest progress in the field.
