Abstract: Photonic Crystal fibers consisting of defect region at a center surrounded by multiple air holes running along its length have been the topic of most interest of researchers because of unique properties over conventional optical fibers. Here basics of Photonic Crystal Fibers, PCFs modeling methods are discussed. A rectangular core photonic crystal fiber structure has been designed based on higher order mode filtering, in which single polarization is obtained with asymmetric design and introducing different loss for x-polarization and ypolarization of fundamental mode. Single polarization single mode operation of a highly birefringent photonic crystal fiber is investigated in detail by using a full vector finite element method with anisotropic perfectly matched layer. The variations of confinement loss and effective mode area of x-polarization and y-polarization of fundamental mode have been simulated by varying the structural parameters of the proposed photonic crystal fiber. At optimized parameters, the confinement loss and effective mode area is obtained as 0.94 dB/m and 60.67 µm2 for x-polarization as well as 26.67 dB/m and 67.23 µm2 for y-polarization of fundamental mode respectively at 1.55 µm. Therefore, 0.75 m length of fiber will be sufficient to get x-polarized fundamental mode with effective mode area as large as 60.67 µm2.
