1. A photonic integrated circuit (PIC), comprising:
an optical interface configured to receive a frequency comb; and
a supercontinuum generation waveguide (SGW) configured to spread a frequency spectrum of the frequency comb to include a first frequency and a second frequency different from the first frequency, wherein the first and second frequencies are selected for stabilizing a repetition frequency of the frequency comb.
