摘　　要：提出一种基于取样长周期光纤光栅制作的多通道带阻滤波器,采用不同的分析方法对其传输特性进行了较详细的分析,分别给出光栅参数与其透射特性和时延特性之间的关系,并得到具有一致性的结果,由此得出的结论对器件的优化设计具有实际指导意义。We demonstrated a new multi-channel band rejection filters based on sampled long period fiber gratings. The characteristics of transmission were analyzed in details. The relationship of the coefficients between the gratings' transmission and dispersion was given, and the consistency conclusions which are significant in optimizing the gratings' design were obtained.
