Dispersion calculation of photonic crystal fibers by the normalization technique
光子晶体光纤色散的无量纲化计算方法

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.
