摘　　要：运用耦合模理论推导了双光纤布拉格光栅的透射率和反射率的解析表达式,利用相关表达式计算和分析了双光纤布拉格光栅的反射特性,并与单光纤布拉格光栅作了比较。讨论了双光纤布拉格光栅反射特性与光栅间距、光栅长度和折射率微扰最大值之间的关系,为双光纤布拉格光栅波长锁定器的设计与制备提供了理论依据。最终获得双光纤布拉格光栅的结构和特性参数,并与实测的数据进行比较,结果表明两者较为一致。The analytical expression of transmissivity and reflectivity of dual Fiber Bragg Grating(FBG) has been given by the coupled mode theory.Using the relevant expression,we analyzed the reflection characteristics of dual Fiber Bragg Grating and compared with single Fiber Bragg Grating.The influences of grating spacing,grating length and refractive index micro-disturber on reflectivity for dual Fiber Bragg Grating have been discussed.It is provided a theoretical basis for design and fabrication of dual Fiber Bragg Grating Wavelength Locker.Finally,the characteristic parameters of FBG and good quantitative coherence between characteristic parameters and experimental results have been obtained.
