中文摘要：

从耦合模理论出发，推导了折射率直流分量调制函数与光纤Bragg光栅相位之间的关系式，分析了折射率直流分量调制对光纤Bragg光栅时延特性的影响．利用传输矩阵法进行了数值仿真，仿真结果与理论分析一致．在理论分析基础上，提出采用同一块均匀相位掩膜版灵活制作具有不同线性或非线性时延特性的啁啾光纤光栅的方法，可用于高速光通信系统中不同色散和色散斜率的补偿．

英文摘要：

The relationship of refractive index direct current component modulation function and phase of fiber Bragg grating was deduced using coupled-mode theory,and the effect of refractive index direct current modulation on fiber Bragg gratings was analyzed and the numerical simulation investigation with Transmission Matrix Method was also given. The simulation results agree with those theories reported in literatures. Based on the theoretical analyses, by properly controlling the RIDCC modulation, using the same uniform phase mask can fabricate fiber Bragg gratings with different linear or non-linear group delay characteristics. These gratings can be used for different dispersion compensation and dispersion slope compensation in high-speed optical Communication systems.
