摘　　要：本文对采用取样非线性啁啾光纤光栅用于补偿光通信系统中的动态色散进行了研究。提出了二进制取样非线性啁啾光纤光栅所产生信道个数的计算方法。对不同长度的取样光栅的一阶啁啾系数c1和二阶啁啾系数c2的取值范围进行了研究,并进行了数值仿真。It is proposed that the nonlinearly dynamic chromatic dispersion in the optic communication system can be compensated by using sampled nonlinearly chirped fiber Bragg gratings(SNLCFBG). We make the numerical simulation and then analyze the spectrum character and time delay. At the first time, the method about which calculate sthe channel number抯 of the SNLCFBG the are suggested . The limitregion of c1 抯 and c2抯 vaule is analysed. The numerical simulation about dispersion compensation is made by use of the SNLCFBG.
