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 CW powers to pump the nonlinear optical process. We retrieved the nonlinear refractive index n2=(5.31±0.04)×10−19m2/W of 3C SiC and observed a signal attributed to Raman gain in the structure.
