| 摘 要： | 基于线性啁啾光纤布拉格光栅的色散补偿原理，探讨了不同的准高斯型耦合系数函数曲线对色散补偿特性的影响，建立使该光栅色散补偿曲线既具有高色散系数和宽带特点，同时对边峰还有相对的抑制能力的设计思想。文中讨论了相关参数对色散补偿曲线的影响。

Optimization of the Linearly Chirped Fibre Bragg Grating |
| |
| Abstract: | Based on the principle of dispersion compensation with linearly chirped fibre Bragg grating (LCFBG)，the different capability of LCFBG varying the quasi-Gauss head coupling profile was analysed. A design is presental which can make the LCFBG provide both strong ability of dispersion equalization and smoothed broad bandwidth GVD curve with depressed sidelobes. The influence of relative parameter to the GVD curve is discussed. |
