摘要
分析了光纤布拉格光栅构成的法布里_珀罗 (F_P)腔的透射谱特性 ,讨论了光栅带宽 ,反射系数相位因子以及腔长对F_P腔透射特性的影响 ,并对F_P腔随温度和应变的特性进行了分析 ,然后给出如何设计在光栅中心耦合波长处单模运转的法布里_珀罗腔 .并提供了数值模拟结果和实验结果 .
The characteristics of transmission spectrum of Fabry-Perot(F-P) cavity composed of two fiber Bragg gratings(FBG) are analysed in this paper. As the influence factors, bandwidth of FBG, phase factor of reflection coefficient of FBG and length of cavity are included. The changes of its characteristics caused by temperature and strain are dicussed. Then the method of how to design this kind of F-P cavity with single mode at the Bragg wavelength of FBG is provided. The numerical simulation spectrum and experimental result are also given.
