Quiet point hunting with PWBs. (a) Soliton spectra for a range of laser-resonance detunings from 3 to 5 MHz, where the modal crossings become visible after 4 MHz. (b) Visualization of the shift in microresonator repetition rate as a function of detuning. Point 1 indicates a normal operating point where the FSR varies linearly with detuning and Point 2 suggests a quiet point where the FSR versus detuning relation is effectively invariant. (c) Plot of the phase noise for the two points in (b) indicating around 10 dB noise suppression for point 2.
