Photonic Crystal Microring Resonator on a Hybrid Silicon Nitride-on-lithium Niobate Platform

We demonstrate a photonic crystal resonator on hybrid silicon nitride-on-lithium niobate (SiN-on-LN) platform, designed for microwave-assisted optical-frequency conversion applications. We measure a large intrinsic quality factor (Qint) of 1.47×105 with mode-splitting bandwidth of 14.6 GHz.
