Abstract

We demonstrate efficient four-wave mixing in high Q 4H-SiC microring resonators. We achieve a four-wave mixing conversion efficiency of -21.7 dB in a microring resonator with 79 mW pump power. Thanks to the strong light confinement in SiC waveguides with sub-micron cross-section dimensions, a high nonlinear parameter (γ) of 12.5 W-1m-1 is obtained, from which the nonlinear refractive index (n2) of 4H-SiC is estimated to be 9.2±0.4×10-19 m2
