摘　　要：设计一种新型椭圆纤芯带隙型光子晶体光纤模型,利用有限元法及其平面波展开法研究子晶体光纤的光学特性.在一定结构参数下随波长的变化数值模拟了椭圆纤芯带隙光子晶体光纤的结构,得到了有效折射率、双折射、波导色散、径向传输功率分布最大值等性质.数值模拟结果表明,选择合适的结构参数可以得到较低的色散特性以及高的传输功率,因此非对称结构的光子晶体光纤的特性分析对于光学器件的研制有重要意义.In this paper,a new unsymmetrical dual- core photonic bandgap- photonic crystal fiber model is designed by using finite element method and its twin- core fiber coupling characteristics of the optical properties of the photonic crystal fiber. Numerical simulate is simulated by the variation of the wavelength of effective index of refraction,birefringence,coupling coefficient that unsymmetrical dual- core photonic crystal fiber with certain structural parameters. The results show that the choice of appropriate structure parameters can be to obtain high birefringence characteristics and coupling characteristics.Therefore,the analysis of the characteristics of photonic crystal fiber with asymmetric structure has important implications for the development of optical devices.
