Abstract

Self-electro-optic effect devices (SEEDs) have recently received much attention due in part to their versatility and performance. However, the work to date has concentrated on electro-optic modulators which respond in some way to an optical signal. A report is made here on results obtained with a GaAs/AlGaAs multiple quantum well directional coupler configured as a SEED device. A robust optical switching operation is demonstrated with a high contrast ratio and constant output power.
