All-optical signal processing functions using semiconductor ring lasers

Abstract

A semiconductor ring lasers (SRL) device is formed when the optical gain waveguide forms a closed loop. Such a laser supports two possible directions of lasing, clockwise (CW) and counter-clockwise (CCW), which can be used to represent binary values ‘0’ and ‘1’. The SRL is therefore a bistable device. Importantly it was discovered that the SRL bistability was self-sustaining [1], and can be set and reset optically [2].
