Abstract
We report on theoretical and numerical investigations of stimulated Brillouin scattering (SBS) in optical fibers. A theoretical framework is presented which involves a nonlinear triply-coupled time-dependent system of equations containing the optical, Stokes, and phonon fields. We examine short fibers where previous approximations for long fibers cannot be made. We consider modulation frequencies and linewidths starting at approximately the Brillouin gain bandwidth and all the way up to frequencies of the order of the Brillouin resonance frequency. We provide simulations showing the SBS suppression factor as a function of modulation amplitude and frequency for a single-sinusoidal modulator.
