Paper Abstract

Modal solutions for photonic crystal fibers (PCFs) with circular air holes in a hexagonal matrix are presented, using a rigorous full-vectorial finite element-based approach. The effective indices, mode field profiles, spot-sizes, modal hybridness, modal birefringence and group velocity dispersion values have been determined for a representative range of PCFs and the results obtained are shown and conclusions drawn. The effect of the structural asymmetry and modal confinement on the optimization of the modal birefringence is also thoroughly studied and presented here. The effect of total power on the effective indices and spot-sizes of nonlinear PCFs is also presented.
