摘要

在edfa中，传输光束很少考虑非线性光学。本文研究了掺铒光纤放大器中受激布里渊散射(SBS)的影响。本文将介绍一个预测受SBS影响的edfa增益的模型。建模和仿真结果表明，SBS会引起泵浦光的后向散射，导致edfa的增益减小，而这种增益减小取决于泵浦光的线宽。数值结果表明，这种增益降低存在一个阈值。得到了使SBS引起的增益降低最小的激光线宽阈值。

Optimization of pump characteristics for the EDFAs considering the effects of stimulated Brillouin scattering

Nonlinear optics is hardly considered on propagated beam in EDFAs. In this paper we will study the effects of the stimulated Brillouin scattering (SBS) in erbium doped fiber amplifiers (EDFAs). A model for predicting gain of the EDFAs that affected by SBS will be introduced. The results of modeling and simulation show that the SBS will cause backward scattering of the pump light and causes a reduction in the gain of EDFAs and this gain reduction depends on the pump laser linewidth. The numerical results show that there is a threshold value for this gain reduction. The threshold value of laser linewidth for minimizing the gain reduction due to SBS will be obtained.
