Process Technology for Semiconductor Lasers describes the design principles of semiconductor lasers, mainly from the fabrication point of view. Starting out with the history of semiconductor-laser development and applications the materials for use in lasing from short to long wavelengths are reviewed. The basic design principles for semiconductor- laser devices and the epitaxy for laser production are discussed. An entire chapter is devoted to the technology of liquid-phase epitaxy, and another one to vapor-phase and beam epitaxies, respectively. The characterizations of laser materials, and the fabrication and characteristics of semiconductor lasers are treated. Mode-control techniques are presented, and surface-emitting lasers are introduced in the final chapter.
