Abstract :
Based on phase manipulation of optical frequency combs and square-law detection of the waveforms, low phase-noise frequency with its tunable repetition frequency ranging from 10GHz to 120GHz is generated using a dispersive medium fed by coherent optical frequency combs with frequency interval controlled by pulse pattern generator. Both temporal waveforms and phase noise are evaluated. The phase noise of generated 40GHz tone is -96.9dBc/Hz at 10 kHz offset.
