Abstract

Stimulated Mandelstam-Brillouin scattering (SMBS) is experimentally studied in a fiber-optic communication line at a high power of the transmitted signal. The SMBS threshold is not observed at a power of up to 400 mW, which is due to an alternative nonlinear effect (self-phase-modulation (SPM)). An analytical model of SMBS in a single-mode fiber is developed with allowance for SPM. The theoretically estimated power of spontaneous scattering is substantially lower than the power obtained in the absence of SPM. The SMBS efficiency is plotted versus the spectral width of the signal at the input of the communication line. It is demonstrated that the SMBS effect is negligibly weak when the initial spectral width of the signal exceeds a certain threshold level.
