| 摘 要： | 设计了一种用于买现低损耗、近零超平坦色散特性的光子晶体光纤结构,这种结构光纤包层空气孔层数少,内三层空气孔直径相同,制作过程简单;应用多极法研究了此结构PCF各个参数特别是最外层空气孔直径对色散和损耗特性的影响,通过优化结构,设计出了在1.3μm至1.65μm波长范围内色散绝对值小于0.5ps/（nm.km）,1.55μm处损耗为4.5dB/km的低损耗近零超平坦色散光子晶体光纤。

| Abstract: | A photonic crystal fiber structure with low loss and nearly zero ultra-flattened dispersion was designed,which had few air holes in the cladding.The air holes of three inside layers had the same diameter,so it was easy to fabricated.The effects of the structural parameters especially the diameter of the outside layer on dispersion and loss properties was studied by the multipole method.At last the photonic crystal fibers with low loss and nearly zero ultra-flattened dispersion was obtained,the absolute valu... |
