文摘

The vector model on the polarization properties of stimulated Brillouin scattering is analyzed theoretically with the Stratonovich generator. The quantitative characteristics of average Brillouin gain and alignment of pump and signal waves are numerically investigated. Simulation results show a more general conclusion about the state of polarization that corresponding to the maximum Brillouin gain, when a wider range of birefringence value is considered. In addition, the fluctuation range of signal output is presented. Finally, the statistics of signal output is studied and found to be Gaussian distributed in log-scale. The detailed quantitative study contributes to further understanding of the effect of polarization and birefringence on stimulated Brillouin scattering and statistics of Brillouin gain.
