Square and triangular lattice of air holes Varying dispersion characteristics of micro-fiber comparison of the article: Wu Jinqing Xuewen Rui Zhou Guosheng, Category: Mathematics Science / Natural Science, file Abstract: Daquan Chinese newspapers and magazines, collecting more than 7000 kinds of description ...

方形和三角形格点分布渐变空气孔微结构光纤的色散特性比较》文章作者：武劲青薛文瑞周国生，分类：数理科学/自然科学，文件摘要：中国报刊杂志大全，搜集介绍7000多种。。。

The mode field of photonic crystal fiber structured with hexagon symmetry hole cladding was analyzed by coupled-mode, and the effective indexes of base mode of different wave length were got. The characteristics of this photonic crystal fiber grating were computed and simulated by coupled-mode method and transmission matrix method. Moreover, the differences were compared between conventional fiber grating and photonic crystal fiber grating on their reflection spectrum and delay.

利用多极法对包层空气孔为正六边形对称结构光子晶体光纤的模式场进行了分析，计算出不同波长下基模的有效折射率，结合使用模式耦合理论和传输矩阵法对基于光子晶体光纤的布拉格光栅特性进行了计算和仿真，对比了常规单模光纤所成光栅与相同光栅周期的光子晶体光纤布拉格光栅反射谱及时延特性之间的差异。
