Abstract

A photonic microwave mixing apparatus and method thereof are disclosed. An optical input carrying a frequency-to-be-converted microwave signal is injected into a photonic microwave mixing module of the photonic microwave mixing apparatus, wherein the photonic microwave mixing module includes a microwave mixing laser. The optical power and carrier frequency of the optical input are adjusted so as to place the microwave mixing laser in period-one nonlinear dynamics, and, at the same time, to achieve frequency-unlocking between the oscillation sidebands of the period-one nonlinear dynamics and the modulation sidebands of the optical input. Under such operation, the microwave mixing laser emits a nonlinear wave-mixing optical signal. Properly selecting the frequency components of the nonlinear wave-mixing optical signal through an optical frequency component selector generates an optical output carrying a frequency-converted microwave signal, therefore achieving microwave frequency conversion.
