摘　　要：基于耦合模理论,运用传输矩阵法对取样光栅的反射谱进行了数值计算,着重分析了光栅长度、占空比及光栅取样周期对取样光栅反射谱的影响规律,基于特性分析讨论了取样光栅在光纤系统中的应用,为以后具体应用提供了理论指导和参考。Based on coupled-mode theory the reflection spectrum of sampled fiber grating is numerically calculated utilizing transmission matrix method. The affection rules of fiber grating length, duty factor, and sampled period of the fiber grating on the reflection spectrum of the fiber grating are emphatically analyzed. The application of sampled fiber grating in optical fiber systems is discussed based on the characteristics so as to offer theoretical guidance and reference for its future concrete application.
