Fig. 3: Diffusion coefficient and responsivity.
From: Quantum decoherence of dark pulses in optical microresonators

a Jitter spectral density at different ASE power level. ASE noise generated from an EDFA is combined with the continuous-wave pump and sent into the microresonator. b Diffusion coefficients (Lorentzian linewidth of repetition frequencies) versus ASE power. The red line is a linear fit. c Measured jitter responsivity as a function of relative mode number.
