Abstract
We demonstrate self-seeded, broadband comb generated in a monolithic highly nonlinear fiber res- onator. When pumped with a CW 1550-nm laser, the fiber cavity generates a comb with two characteristic spacings. Hyperparametric modes spaced by 2 THz create the base structure of the comb while commensurate Brillouin modes spaced by 10 GHz populate the intermediate frequency gaps. The frequency modes are coherent, and the repetition rate of the comb may be locked.
