Fig. 4: Transmission spectra and relaxation of SiC resonator at high power.

a Transmission spectra of the probed resonance at 1547 nm with a 1544 nm wavelength pump of varying powers (see colorbar) launching into the VGC to excite the resonator. b Step response showing the probe resonance after the pump beam (500 mW power) is switched off. The exponential decay is due to thermal relaxation.
