Four wave mixing in 3C SiC ring resonators

We demonstrate frequency conversion by four wave mixing at telecommunication wavelengths using an integrated platform in 3C SiC. The process was enhanced by high-Q and small modal volume ring resonators, allowing the use of mW-level continuous wave powers to pump the nonlinear optical process. From this measurement, we retrieved the nonlinear refractive index of 3C SiC as n2=(5.31±0.04)×10−19m2/W.
