摘要

Cascaded chirp fiber Bragg grating has been analyzed through coupled mode equations method and transfer matrix method.A wide bandwidth,big dispersion value,and low delay ripple cascaded chirp fiber Bragg grating as a dispersion compensator is analyzed and designed based on the parameters of an 8× 160Gb/s high speed quasi-linear optical transmission system.The simulation result of system performance,the Q value of 7.15～ 8.74 of each channel confirm the success of the design of the cascaded chirp fiber Bragg grating.%用耦合模理论和传输矩阵法对级联啁啾布喇格光纤光栅进行了分析,设计了一个大带宽、高反射率、大色散、低时延波纹的级联啁啾光纤光栅,并将其应用到一个8信道160Gb/s的高速准线性光传输系统中进行色散补偿.系统仿真结果表明,各个信道的Q值均在7.15 ～ 8.74之间,实现了级联啁啾光纤布喇格光栅的设计目标.
