摘　　要：根据非线性啁啾光纤光栅可用于对光通信系统中一阶和二阶色散进行补偿的原理 ,系统地研究了二类取样型非线性啁啾光纤光栅的反射谱及时延特性 ,并进行了数值仿真。提出了计算二类取样光栅产生的信道数的计算方法。According to the principle that linearly and quadration chromatic dispersion in the optic communication system can be compensated by using a nonlinearly chirped FG's (NLCFG's), we analyze the reflect spectrum and time delay of two kinds of sampled nonlinearly chirped fiber gratings and make the numerical simulation. The computational method of multichannel numbers about sampled NLCFG's is proposed.
