Abstract

A comparison of different schemes to enhance stimulated Brillouin Scattering (SBS) in single-mode optical fiber is performed. Specifically, we evaluated SBS generation efficiency in a 3 km length fiber with and without power recycling versus the same fiber placed in a ring resonator and in a ring resonator in a recycling configuration. For the latter case, a large number of both odd and even higher-order Stokes and anti-Stokes harmonics is generated. We show that the choice of the scheme is dictated by specific application. In addition, when incorporating a ring resonator in a Sagnac loop, a flat optical frequency comb is generated.
