On-chip entangled photon-pair generator on the SOI platform
This work reports recent progress in developing silicon photonic circuits for on-chip generation and manipulation of entangled photon pairs. We successfully integrated three essential functions— photon-pair source, pump filtering, and demultiplexing—into a single silicon chip. Key performance results include a high-quality resonator (Q-factor > 100,000), pump rejection over 80 dB, and efficient signal-idler separation with minimal crosstalk (better than 40 dB). These advancements pave the way for high-brightness photon-pair generation and manipulation, beneficial for quantum applications.
