Abstract

The light amplifying optical switch (LAOS) consists of a he tero junction phototransistor (HIT) vertically integrated with a light-emitting diode (LED). The device exhibits s-shaped, negative differential resistance which creates bistable, or switching, characteristics. It has proven to be a very versatile device, as it is cascad able, produces optical gain, and can be used to perform a variety of logic functions.1
