From: Efficient Kerr soliton comb generation in micro-resonator with interferometric back-coupling
The input pump power is a 50 mW, b 68 mW, c 80 mW, and d 140 mW. Perfect soliton crystals steps are observed for Pin = 50, 68, and 80 mW. Multi-soliton steps are observed at 80 and 140 mW. For 80 and 140 mW pump powers, the step height changes for different scannings. The soliton crystal with defect spectrum shown above c exhibits a typical spectrum generated at 80 mW, for the detuning that is indicated with a black arrow. e MI (blue line) and PSC (red line) spectra. Measurement of the effective pump detuning for the f PSC and g MI combs. The black arrow in f–h indicates the center of the resonance. The panel below g shows the details of the beating between the pump and the probe. The case in h shows the smallest detuning that we could measure in a PSC.
