abstract
We study a re-configurable nonreciprocal fiber ring cavity setup to generate tunable optical frequency combs. Coherent combs can be obtained by finely exploiting bi-chromatic Brillouin lasing and cascaded four-wave mixing in the nonlinear fiber cavity. We introduce a numerical model of the cavity system, which is validated by comparisons with experiments. Our work shows the importance of the mode pulling effect, controlled by the pump laser detuning, in setting the dynamics of the comb. This effect along with the impact of multimode lasing had been overlooked in previous fiber experiments. We discuss these limitations and devise several scaling laws for these system.

Fast and accurate modelling of Kerr-Brillouin combs in Fabry-Perot resonators
A new mean-field model, a Fabry-Perot Lugiato-Lefever equation with a nonlocal Brillouin response, reproduces coupled-wave simulations of Kerr-Brillouin combs while speeding up computation by up to four orders of magnitude.
