Δ(δ20) is changed by applying electrical power on a thermal heater. a The measured average Q-factor as a function of the electrical power is depicted in squares while the calculated values from Eq. (1) are shown in a solid line. The percentages in red are the conversion efficiencies ϵ as calculated from experimentally obtained PSC spectra while varying Δ at a constant input pump power. b Output comb power obtained by numerical simulation sweeps of the detuning, δ1, for different values of input pump power.
