Evaluation of stimulated Brillouin scattering in a single-mode fiber in backward and forward directions with heterodyne detection technique

摘要

Stimulated Brillouin Scattering (SBS) in a single-mode optical fiber in backward and forward directions has been evaluated with heterodyne detection technique at 1550nm region. Experimental result of forward direction SBS can be described well by a theoretical model based on Rayleigh back scattered power of ordinary backward SBS.
