An elliptical-hole photonic crystal fiber with double defect is proposed, which is supposed to be achieved by extruding a normal circular-hole photonic crystal fiber. By employing a full-vector finite-element method (FEM) and anisotropic perfectly matched layers, the birefringence and the confinement loss of the proposed highly birefringent photonic crystal fiber with double defect are investigated, respectively. Simulation results show that the birefringence of the proposed photonic crystal fiber can be up to the order of 10-2.
