PHOTONIC MICROWAVE GENERATION APPARATUS AND METHOD THEREOF

摘要

A photonic microwave generation apparatus and a method thereof are disclosed. A comb-like optical signal generation module of the photonic microwave generation apparatus generates a comb-like optical signal. The comb-like optical signal is injected into a photonic microwave generation module of the photonic microwave generation apparatus, wherein the photonic microwave generation module includes a microwave generation laser. An optical power and a carrier frequency of the comb-like optical signal are adjusted so as to place the microwave generation laser in period-one nonlinear dynamics, and, at the same time, to phase-lock an oscillation sideband of the period-one nonlinear dynamics by one harmonic of the comb-like optical signal. Under such operation, the microwave generation laser emits an output optical signal that carries a microwave signal of a narrow linewidth and a stable frequency, which can be retrieved from the output optical signal by using a photodetector.
