摘要

光纤内部残余应力对布里渊光谱特性有显著影响。我们分析了内应力对常规G.652光纤布里渊增益谱(BGS)的重要性，并将建模结果与测量结果进行了比较。然后研究了一组沟槽辅助纤维的残余内应力:不同拉伸张力的纤维来自单一预制棒。基于实测内应力剖面的数值模拟与相应的BGS实验结果进行了比较。显然，布里渊谱随拉伸张力线性移位，其线宽增加，系数为-20MHz/100g。

Importance of residual stresses in the Brillouin gain spectrum of single mode optical fibers.

Residual stresses inside optical fibers can impact significantly on Brillouin spectrum properties. We have analyzed the importance of internal stresses on the Brillouin Gain Spectrum (BGS) for a conventional G.652 fiber and compared modeling results to measurements. Then the residual internal stresses have been investigated for a set of trench-assisted fibers: fibers are coming from a single preform with different draw tensions. Numerical modeling based on measured internal stresses profiles are compared with corresponding BGS experimental results. Clearly, Brillouin spectrum is shifted linearly versus draw tension with a coefficient of -20MHz/100g and its linewidth increases.
