| 摘 要： | 利用多极法对八边形光子晶体光纤的色散补偿特性进行数值模拟,分析了结构参数变化对色散补偿特性的影响;计算了具有相同参数的六边形结构光子晶体光纤的色散系数和非线性系数;研究表明八边形光子晶体光纤比六边形结构的光子晶体光纤的大负色散特性明显提高,非色散系数低,更有利于进行色散补偿.因此,本文设计了一种新型的八边形色散补偿光纤,在λ=1.55μm时色散值为-1434.9ps·nm-1·km-1,色散斜率为-4.6338ps·nm-2·

| Abstract: | The dispersion compensation property of octagonal photonic crystal fibers(PCFs) was simulated with multipole method in this paper.It was found that the dispersion,dispersion slope and Kappa parameter of PCFs can be designed precisely but changing the air hole size and the pitch in PCFs cladding.We compared photonic crystal fiber of hexagonal structure with that of octagonal structure,both of which have the same structure parameters.It was found that the octagonal structure easily abtains large negative disp... |
