摘要
本文利用耦合模方程，对具有不同函数形状耦合系数的光纤光栅的色散特性进行了理论和数值研究．通过比较这些线性咽啾光纤光栅对１０Ｇｂ／ｓ光通信系统色散补偿的效果，揭示了光纤光栅的耦合系数与其色散补偿性能的关系．
It is analysed theoretically and numerically the dispersion of the linearly chirped fiber gratings with different coupling profiles. The numerical simulations of the fiber gratings with the different coupling profiles for dispersion compensation at 10Gb/s of standard optical fiber are given. The results show that the linearly chirp fiber gratings coupling profiles produce a great impact on their dispersion cancellation in long distance.
