Extended Data Fig. 4 | Frequency-dependent transduction of carrier
modulation from pump to comb sidebands. a, Time-dependent frequency of
pump laser at 193 THz (grey) and 195 THz comb sideband (μ = 20, dark green)
and modulation frequency 100 kHz. b, As for a, but for modulation frequency
10 MHz. c, Power spectral density of frequency modulation Sff for pump (grey)


and sideband (dark green). The markers denote the positions of harmonics,
which are used in the transduction analysis. The lower panel shows the power
spectral density of sideband frequency modulation harmonics normalized to
the corresponding modulation power spectral density of the pump laser (see
Fig.  3 ). d, As for c, but for modulation frequency 10 MHz.
