Optical Generation and Control of Microwaves and Millimeter-Waves

I report the generation and control of microwaves and millimeter-waves by optoelectronic techniques. Complete time synchronization between microwave and optical signals is achieved. RF waveform generations, ranging from one single cycle to continuous wave with peak power up to a few kilowatts, have been demonstrated. Laser controlled phase shifters, switches and modulators at 94 GHz are described. The state-of-the-art in the general area of microwave optical interactions is reviewed.
