SIGNAL AMPLIFICATION USING OPTICALLY ACTIVATED BULK SEMI-INSULATING GAAS

摘要

Bulk gallium arsenide having a high hold-off voltage is optically activated by a laser resulting in high power output. A high voltage input is applied to a semi-insulating gallium arsenide material. The gallium arsenide material is activated by laser light, thereby resulting in large current conduction. An external oscillating signal is superimposed on the high current resulting in a high power output.
