Combination of full-vector finite element method with anisotropic perfectly matched layers results in a novel structure of low-dispersion photonic crystal fiber with high birefringence. The negative dispersion can be obtained at a wavelength of 1.55 μm by adjusting the lattice constant Λ and the round air hole diameter d. Numerical results show that the dispersion variation is negative in the C band, the dispersion slope values are between 0.112 and 0.142 ps·km-1·nm-2 over the C band, and the birefringence is 5.7×10-3.
