4H-silicon carbide (SiC) integrated platforms have shown great potential in quantum and nonlinear photonics. However, the thermal properties of 4H-SiC waveguides are still unknown, even though thermo-optic effects can play an important role in fundamental measurements and practical applications. In this paper, we comprehensively study the thermo-optic effects in a 4H-SiC microring resonator, by means of both temperature tuning and self heating.
The thermo-optic coefficient and the ratio between the thermal absorption and the thermal diffusion of 4H-SiC are quantitatively measured to be 4.21 × 10−5 K−1 and 14.9 K W-1, respectively. Taking the acquired thermal properties into account, we experimentally achieve Kerr-nonlinearity based dual-pump optical parametric oscillation (OPO), and thus demonstrate that broadband solitons could feasibly be generated through thermal tuning of 4H-SiC-oninsulator (SiCOI) microring resonators.
