Semiconductor-Laser Physics discusses the underlying physics and operational principles of semiconductor lasers. The optical and electronic properties of the semiconductor medium are analyzed in detail, including quantum confinement and gain engineering effects. A semiclassical and a quantum version of the laser theory are presented, including an analysis of single- and multimode operation, instabilities, laser arrays, unstable resonators, and microcavity lasers.
