Hybrid on-chip microwave photonic signal processor architecture

We present a new microwave photonic signal processor architecture, where a thin film attenuating counter propagating optical phase locked loop (ACP-OPLL) is integrated with a novel finite impulse response (FIR) optical phase modulator/processors. The realization of the processor requires heterogeneous photonic integration between LiNbO3 thin film electro-optic modulators, SiN ultra-low loss optical waveguides, and III-V high power photodetectors. The microwave photonic signal processor architecture can perform analog signal processing functions with a superior dynamic range performance and frequency response.
