Fig. 6. Pump laser RIN and estimated limitation on the phase noise.
a Optical RIN of the pump laser (green) and microwave amplitude noise of the soliton repetition rate (purple). b Phase noise spectrum of the repetition rate in the quiet point (blue) and estimated limitation from the pump laser RIN (green). The grey curve corresponds to the estimated AM-to-PM conversion in the photodiode (microwave amplitude noise scaled by −25 dB).
