Observation and characterization of deterministic chaos in stimulated Brillouin scattering with weak feedback

Abstract
We report the observation and characterization of chaos in stimulated Brillouin scattering (SBS) generated in a single-mode fiber in the presence of weak external feedback. We establish that the noise, which initiates this process and dominates the emission near the SBS threshold, is dramatically suppressed from the onset of strong SBS emission, giving rise to various highly deterministic dynamical features.
