摘要
文章对分析相移光栅的Agrawal G P理论模型与Turan Erdogan理论模型做了对比研究,结果表明:前者一般适用于均匀相移光栅,而后者适用于各种相移光栅。多层薄膜模型可用于各种相移光栅的研究,当多层薄膜的划分层数达到20时,满足计算精度要求。
Agrawal G P and Turan Erdogan models of analyzing phase-shifted fiber grating are compared,the numerical calculation results show that the former is suit for homogenized phase-shifted grating,the latter is suit for all kinds of phase-shifted gratings.Multiple-thin films' model can be suit for all kinds of phase-shifted gratings'study,calculation accuracy satisfies design demand when slice of thin film is 20.
