Bistable Photoconductive Switches Particularly Suited For Frequency-Agile, Radio-Frequency Sources.

Abstract

A photoconductive switching device is disclosed that has an enhanced speed of response so that its closed (low) and open (high) resistive states are obtained in response to optical illumination in the less than nanosecond regime. The enhanced speed of response is achieved by neutron irradiation of a material preferably comprising GaAs:Si:Cu. An application of the improved photoconductive switching devices is disclosed which allows the realization of a high power, frequency agile RF source topology.
