Extended Data Fig. 4: Optical power requirements.

Estimated optical power to reach a specified phase noise floor or SNR in (a) the detection of the 20 GHz microcomb, and (b) the beat note between the SIL lasers and microcomb. The dotted line represents the required performance to achieve the results presented in the paper. The calculations assume a photodetector quantum efficiency of 0.5.
