Abstract
Embodiments herein describe generating signals for stabilizing a frequency comb using a PIC that contains a two-segment supercontinuum generator waveguide (SGW). A first segment of the SGW is designed to spread the spectrum of the frequency comb so that a significant portion of the spectral intensity of the frequency comb is at double the original frequency of the frequency comb. A second segment of the SGW is designed to spread the spectrum of the frequency comb so that a significant portion of the spectral intensity of the frequency comb is at a frequency of a reference laser.
