摘要
The calculation of chromatic dispersion in silica-based photonic crystal fibers is discussed. A perturbative approach to the inclusion of material dispersion is presented, and it is shown that this method can give accurate predictions for a wide range of physical fiber dimensions on the basis of a single waveguide dispersion calculation. Furthermore, it is demonstrated that a proper choice of the transverse k vector in a supercell calculation can significantly improve the convergence of the results with respect to supercell size.
