The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

We consider stimulated Brillouin scattering excited in a "feedback-free" optical fiber by continuous wave monochromatic pump radiation. We show the Stokes signal displays stochastic dynamic behavior from its onset. On increase of the pump signal a window of periodicity emerges from and subsequently subsides into the stochastic emission, the period of which corresponds to the round-trip time in the fiber. We show this feature arises from coherent regenerative amplification of the stochastic spontaneous Brillouin scattering due to minute residual feedback.
