Towards Kerr optical frequency combs in a Brillouin fiber laser cavity

In this contribution, we investigate a simple and reconfigurable all-fiber ring cavity to generate tunable Kerr optical frequency combs in both 1.55-and 2-µm spectral bands. We demonstrate that coherent frequency combs can be obtained by finely exploiting both stimulated Brillouin backscattering and cascaded four-wave mixing in the nonlinear fiber cavity.
