Abstract
Stimulated Brillouin scattering(sBs) is the most dominant nonlinear process in optical fibers. It is a laser induced acousto-optic phenomenon with inherent optical feedback. As such, it is inherently quasi-periodic and chaotic in nature. The critical factors of fiber length, power, and feedback work together in producing this complex behavior. The Brillouin Fiber Ring greatly reduces the SBS linewidth as opposed to the open-ended scheme on the one hand, but enhances nonlinear dynamical instabilities such as quasi-periodicity and chaos. There is a rich variety of temporal behavior that flows through a seemingly automatic process of change above threshold. Increasing input power causes the dynamical behavior to further change while for some powers induces a change in line position or creates multiple lines in the frequency domain. The origin of these instabilities is being studied, while developing a means to suppress them.
