The stress-induced single-polarization properties of large-mode-area photonic crystal fiber were calculated through finite element method with implying the perfectly matched layer (PML). The effects of core parameters on the polarized behavior was studied. Results indicate that the confinement loss ratio ( CLR) of the two polarized modes decreases with the increasing of refractive index. The field distribution coefficient becomes small when the core diameter is reduced.
