ABSTRACT:
A quantum well laser exhibiting near ideal switching characteristics, high power conversion efficiency and, moreover, capable of utilizing the advantageous characteristics of a double heterostructure optoelectronic switch comprises a quantum well region disposed between carrier confinement regions. In particular, the interface between the qunatum well regioin and a confinement region is adapted to the formation of an inversion layer.
