High-Bandwidth, Low-Insertion-Loss Nonreciprocal Transmission Based on a Chiral Silicon Microring

We demonstrate a nonreciprocal transmission in photonic integrated circuits based on a chiral silicon microring. Nonreciprocal light propagation is achieved with a nonreciprocal bandwidth exceeding 15 GHz and an insertion loss below 0.2 dB.
