摘　　要：深入研究了线性啁啾光纤光栅受到轴向应力时的偏振相关损耗(PDL)特性,并对不同轴向应力下的偏振相关损耗特性进行了大量实验研究,实验表明偏振相关损耗特性对轴向应力的响应非常敏感,压力变化使峰的移动比较明显,从而可以利用PDL的特性对外场信息进行灵敏的检测.Base on this existing theories mode, the grating polarization dependent loss （PDL） characteristics of the linear chirped fiber impacted with axial stress are researched, and a large number experimental research to different axial stress the PDL characteristics are proceeded. The result of experimental indicates that PDL characteristics is sensitive to axial stress response, and the variation of the axial stress makes that the peak position shift is obvious. Thereby, Based on the PDL characteristics, the sensitivity to external field information is detected.
