Using a full-vector finite-element method, we calculate modal properties in index-guiding photonic crystal fibres. The influence of the deformation of the geometry in actual fibre structures is evaluated and compared to the idealized-model. These results are applied to the supercontinuum generation. Moreover, development of MATLAB softwares for FEMLAB 3.1 are presented.
