SIGNAL AMPLIFICATION USING OPTICALLY ACTIVATED BULK SEMI-INSULATING GAAS

摘要

Bulk gallium arsenide having a high hold-off voltage isoptically activated by a laser resulting in high power output. Ahigh voltage input is applied to a semi-insulating galliumarsenide material. The gallium arsenide material is activated bylaser light, thereby resulting in large current conduction. Anexternal oscillating signal is superimposed on the high currentresulting in a high power output.
