摘　　要：采用无量纲色散的概念研究了光子晶体光纤色散的计算方法 .利用无量纲色散和波导色散之间的关系单独求解波导色散 ,波导色散和材料色散之和为光子晶体光纤的总色散 .探讨了利用无量纲色散方法控制光子晶体光纤零色散点和设计平坦色散光子晶体光纤的可能性 .无量纲色散的引入能够简化光子晶体光纤色散的计算 ,为设计具有适当色散特性的光子晶体光纤提供理论依据 .Dispersion properties of photonic crystal fibers are investigated using the concept of normalized dispersion. The total dispersion of photonic crystal fibers is obtained by summing up the material dispersion and waveguide dispersion, the latter being obtained by exploiting the relation between normalized dispersion and waveguide dispersion. Efforts are also made to study the possibility of shifting the zero dispersion wavelength of photonic crystal fibers and designing photonic crystal fibers with ultra-flattened dispersion by the normalization technique. The introduction of normalized dispersion will simplify dispersion calculation and will be of theoretical significance for the design of photonic crystal fibers with desirable dispersion properties.
