摘要：

A new optical device which functions either as a gated latch or an AND gate is demonstrated. This device utilizes two different wavelengths of input light and is composed of two heterojunction phototransistors (HPTs) vertically integrated with a light emitting diode. The collector-base regions of the two HPTs are fabricated from different band-gap materials and thus, respond to different wavelengths of input light. The device structure was fabricated from InGaAsP/InP epitaxial layers grown by gas source MBE. The gated latch and AND gate are shown to have an on/off contrast ratio of 12 and 6, respectively.
