With the rapid development of microwave photonics technology, high-speed processing and ultra-weak signal detection capability have become main bottlenecks in many applications. Thanks to extremely low timing jitter properties single-photon detectors, combination classical technology may provide a solution break above bottlenecks. In this paper, we first report novel concept (SP-MWP), SP-MWP system with phase shifting frequency filtering functionalities is demonstrated based on superconducting nanowire single photon detector (SNSPD) successive time-correlated counting (TCSPC) module. Experimental results show that an ultrahigh optical sensitivity down −100 dBm has been achieved, bandwidth only limited by detectors. meantime, proposed demonstrates anti-interference capability, which locked trigger TCSPC can be extracted from detected signals combining noise strong interference. The paves way interdisciplinary field quantum mechanism, named photonics.
