摘要

针对PCF（光子晶体光纤）很难同时获得平坦色散和低限制损耗的问题

设计了一种新的可变空气孔的PCF

通过改变包层中空气孔的大小来获得平坦色散和低限制损耗。采用FVFEM（全矢量有限元法）和APML（各向异性完美匹配层）的边界条件对该光纤的结构进行分析

在设定1.55μm处空气孔的有效折射率为1、石英的有效折射率为1.45的条件下进行了仿真计算

结果表明

该光纤在1.25

.78μm波长范围内具有超平坦色散

并且色散值在0±0.68ps/（nm·km）范围内变化

其限制损耗低于10

-3

dB/m。

Abstract

A new Photonic Crystal Fiber（PCF）with flattened chromatic dispersion and low confinement losses is proposed by varying the size of air hole.By employing a Full Vector Finite-Element Method（FVFEM）and Anisotropic Perfectly Matched Layers（APML）

the structure and optical properties of the proposed PCF are analyzed.The simulation is conducted under the conditions that the effective refractive index of air hole at 1.55μm is n

=1 and the effective refractive index of quartz is 1.45.The results show that the proposed PCF has ultra-flattened dispersion of 0±0.68ps/（nm·km）from 1.25μm to 1.78μm wavelength range with confinement losses lower than 10

-3

dB/m across all the wavelength range.
