Optical physics and laser devices in II–VI quantum confined heterostructures

Abstract

We review some of the recent advances in wide-gap II–VI heterostructures, with emphasis on device physics and engineering of quantum confinement in ZnSe-based multilayer structures for blue-green diode lasers and LEDs. An important element in these quantum well configurations are quasi-two-dimensional exciton effects which dominate absorption but are also of relevance in both spontaneous and stimulated emission processes.
