Abstract

In this study the results of the numerical analysis of a new design of birefringent microstructured fibers (BMSFs) containing three rings of identical air holes around an elliptical core with different distances between the rings of holes are presented. The first ring contains two pairs of holes, which are more widely spaced than others. The BMSFs were characterized using the finite element method. Confinement losses for fundamental and higher-order modes were calculated in the spectral range of 0.20 to 2.65 microns. Simulation results show that an optimum configuration of the proposed design existed, for which the widest spectral range of single-mode guidance of fibers was obtained: from 0.2 to 2.3 microns.
