摘　　要：为了理论分析PCF(光子晶体光纤)的损耗特性,采用多极法研究了包层空气孔直径、孔间距和空气孔层数等参数对PCF 1.31和1.55μm波长处损耗特性的影响。结果表明,选择高空气填充率的结构和增加包层空气孔层数都可以降低PCF损耗;通过增大最外层空气孔直径可在保持色散特性不变的情况下显著降低PCF的损耗。该结论可以为设计低损耗特性的PCF提供理论依据。For the numerical analysis of the loss properties of Photonic Crystal Fibers （PCF）, this paper studies the effects of such structural parameters as air hole diameter, space between air holes and the number of air hole rings in the cladding on the PCF loss properties at 1.31 and 1.55 μm by the multipole method. The results show that the loss can he reduced by choosing structures with high air-fill scale and increasing the air hole rings in the cladding and that it can be dramatically decreased by in- creasing the outermost air hole diameter while keeping the dispersion property constant. This conclusion provides a theoretical basis for the design of PCF with low loss property.
