Type II Quantum Well Laser With Enhanced Optical Matrix Elements

摘要

A type II multiple quantum well, 4 constituent active region, optically cladelectrically pumped and optically pumped laser for emitting at a wavelength greater than or equal to about 2.5 microns is disclosed. The active region comprises one or more periods, each period further comprising a barrier layer, a first conduction band layer, a valence band layer and a second conduction band layer.
