基于干涉原理的光纤Bragg光栅反射光谱特性分析

Reflection spectrum characteristics of FBG based on interference principle

  • 摘要: Bragg条件方程是光纤传感技术的理论基础之一,对理解光纤Bragg光栅的传感机理具有重要的理论价值。从光的干涉原理出发研究了光纤Bragg光栅的反射光谱特性,推导出Bragg条件方程。结果表明:利用干涉原理推导出的结果与利用模耦合理论推导出的结果吻合较好。

     

    Abstract: Bragg condition equation is one of the most important fundamental theories for FBG sensor, and has important value for the study of the mechanism of FBG sensors. The reflection spectrum characteristics of FBG were studied and the Bragg condition equation was obtained by the aid of the light interference principle. The analysis shows that the result derived by the light interference principle is consistent with the one deduced by the coupled-mode theory.
