Abstract

We have recently demonstrated that the recovery time of a MQW waveguide directional coupler switch can be significantly improved by carrier sweep out through the application of an electric field perpendicular to the quantum wells.1 The high frequency operation of a number of other MQW devices based on the SEED principle also depend on cross-well carrier transport in transverse fields. In this work, we have carried out a detailed study of the dynamics of charge transfer perpendicular to the quantum wells as a function of both applied electric field and optical power using the quantum confined Stark effect to monitor the sweep-out rate on picosecond timescales.
