ABSTRACT:
An optically controlled MESFET semiconductor oscillator assembly having a MESFET semiconductor which, when voltage biased by a pulsed dc voltage, oscillates at a free running frequency; an optical signal delivery system, such as a light intensity modulator connected to optical fibers; and other oscillator circuitry including a pulse generator. In operation, the pulsed free running oscillation of the MESFET semiconductor can be injection locked to the intensity modulated optical signal delivered via the optical signal delivery system.
