  1. Sensitivity of the SIL microcomb’s offset frequency foff and repetition rate frep to the DFB current Ip and micro-heater current Ih. The values were measured around the experiment set point of  ~180 mA and 3 mA, respectively. A theoretical derivation of the actuator tuning coefficients is presented in Section 1 and 2 of the Supplementary Information.
