摘　　要：介绍了一种遗传算法与离散剥皮法相结合的高信道数取样光栅色散补偿器的设计方法。当用离散剥皮法设计多信道的光栅时折射率调制幅度过大。通过理论分析,发现进一步减小折射率调制幅度是可行的,并求出最小值。运用遗传算法优化各信道的相位,显著减小了光栅折射率调制的幅度。同时详细说明了MATLAB遗传算法工具箱的使用,给出适度函数的具体程序。An design of high-channel-count sampled fiber Bragg grating dispersion compensator with Genetic Algorithm （ OA ） and discrete layer peering （ DLP ） is discussed. When we design multichannel with DLP, the maximum amplitude of the index modulation is too big. By analyzing the theory, we find it is possible to reduce the index modulation, and to gain the minimum .Optimizing phase of channels by GA, we greatly reduce the amplitude of the index modulation, along with expatiating on the usage of toolbox of GA and presenting the program of fitness function.
