Abstract
Microwave-frequency signal generation by generating multiple sideband optical signals separated by phase-modulation frequency f, generating beat signals between one or two sidebands and one or two optical reference signals, generating a loop-filtered error signal by comparing an electrical reference signal to one of the beat signals or their difference, and controlling with the error signal in a phase-locked loop arrangement a voltage-controlled oscillator (VCO) that drives the sideband generation at the frequency f. A portion of the VCO output is the generated microwave-frequency signal.
