摘　　要：提出了一种由光纤光栅、光纤环和光纤方向耦合器组成的全光纤反射器的理论模型,详细地分析了该模型的输出特性,推导出了当光纤光栅为均匀Bragg光栅时,该模型输出光谱与有关参数之间关系的数学表达式,对决定反射器输出光谱特性及其规律的参数进行了详细讨论,其结果可以为今后该器件的制作及关键技术的解决提供参考。A kind of allfiber reflector using fiber directional coupler,fiber loop nad sampling fiber grating is proposed,and its transmission characteristics are studied in detail.The mathematical formulation of the relationship between the transmission spectra out of the filter and relative parameters is obtained when the fiber grating is evenly fiber Bragg grating.Based on this,the reflection spectra graph of the filter is gained under a certain group of parameters given by us.The influence of relative structure parameters on the model transmission characteristics and rules is analyzed,and optimum structure parameters are obtained.The results can provide reference for the facture of this kind of apparatus and the solution of key technology.
