Abstract

A novel GaAs/GaAlAs quantum well optoelectronic switching device, which exhibits an s-type negative differential resistance at room temperature and emits high performance stimulated emission, was demonstrated. The device structure is similar to the conventional separate confinement heterojunction quantum well laser, and thus can be easily integrated with state-of-the-art optoelectronic integrated circuits. The devices can be switched optically and/or electrically. Threshold current densities of 1.2 kA/sq cm, differential quantum efficiencies as high as 67 percent (0.5 W/A slope efficiency per facet) and output power in excess of 50 mW per facet were obtained.
