Patent ID: 7382524

Claim:
A photo-electronic frequency multiplier comprising: an intervening optical signal generator comprising: a light source configured for generating an incident optical signal; a first mirror configured for separating the incident optical signal into first and second optical signals; a first reflector configured for reflecting the first optical signal; a second reflector configured for reflecting the second optical signal; an optical phase modulator configured for modulating a phase of the second optical signal; and a second mirror configured for converting the first and second optical signals into two intervening optical signals; a pair of photo-electronic conversion circuits, each photo-electronic conversion circuit being configured for converting one corresponding intervening optical signal into an electronic signal; a differential amplifier circuit electronically connected with the photo-electronic conversion circuits for multiplying the difference between the two electronic signals and outputting an amplifying signal; and a signal processing circuit electronically connected with the differential amplifier circuit and configured for processing the amplifying signal to generate a signal having a plurality of frequency multiplications.
