Abstract
A photonic microwave time delay apparatus and method thereof are disclosed. The microwave-modulated optical signal generation module of the photonic microwave time delay apparatus generates a microwave-modulated optical signal. The microwave-modulated optical signal is injected into the photonic microwave time delay module of the photonic microwave time delay apparatus, wherein the photonic microwave time delay module includes a microwave-time-delay laser. The optical power and carrier frequency of the microwave-modulated optical signal are adjusted so as to excite the laser cavity resonance red-shift effect in the microwave-time-delay laser. Under such operation, the microwave-time-delay laser emits a microwave-modulated optical signal with a microwave time delay.
