Bistable optical electrical/microwave switching using optically coupled monolithically integrated GaAlAs translasers

摘要

A novel switching device consisting of optically coupled laser and field-effect transistor monolithically integrated on a semi-insulating substrate is demonstrated. The physical origin of the bistable behavior is illustrated. The input and output to this device can take the form of optical and/or electrical signals. Applications of this device in optical, electrical, microwave switching, and pulse-position/pulse frequency demodulation are illustrated.
