Title

All-Optical Switching Of Picosecond Pulses In Gaas Mqw Waveguides

Abstract

All-optical switching has been achieved in zero-gap directional couplers containing either a single or multiple quantum wells. The mechanism which is due to free carrier induced refractive nonlinearities at near band-gap resonant frequencies has an instantaneous turn-on time and a recovery time that depends on the speed at which the carriers are dissipated. A recovery time as short as 130ps has been obtained experimentally by the application of an external d.c. bias which sweeps out the carriers from the quantum wells.
