Abstract
Based on the analysis of birefringence and leakage properties in rectangular lattice photonic crystal fibers(PCFs), we presented a technique of improving the properties of the fibers by the introduction of a doped-core. The influence of pure silica core, silica core with small air-hole, and a doped silica core on the mode profiles of the fiber are investigated and discussed. The influence of doping level on that of birefringence and leakage losses of the fibers is also explored, which is realized by applying the mutipole method. Our numerical simulation proves that, for PCFs with anisotropic claddings, it's possible to obtain an increased birefringence by doping, while maintaining or even reducing the leakage loss by increasing the hole pitch of the fiber. The technique eliminates the disadvantage of deforming mode field by the introduction of small air-hole core and the mode field of the fiber is also increased.
