Wavelength conversion with a high-Q thin-film lithiun niobate microring resonator

Abstract

We report a low-loss thin-film l ithium-niobate-on-insulator p latform, and demonstrated a high-Q microring resonators with a lowest propagation loss of 0.05dB/cm. A wavelength conversion efficiency of -32dB was achieved with 6.6dBm pump power.
