Abstract

Slight geometrical imperfections that can occur during the fabrication process, in the lattice of index-guiding photonic crystal fibers (PCF), are evaluated to determine the sensitivity of the chromatic dispersion and the birefringence to these defects. Furthermore, the impact of fluctuations in the lattice profile of a real photonic crystal fiber on its propagation characteristics is pointed out. Numerical and experimental analyses show that chromatic dispersion of a large core PCF is more robust to the geometrical imperfections, while its birefringence reveals more sensitivity to these defects. This analysis is performed using the finite element method, which assures high solution accuracy.
