The optical properties of near elliptical core polarization maintaining photonic crystal fiber are analyzed by using a full vector model. We classify guided modes in the near elliptical core photonic crystal fibers (PCFs) according to the minimum waveguide sectors and its appropriate boundary conditions. Because the field patterns of the near elliptical core PCF is similar to that of rectangular waveguide, the guided modes are labeled in this PCF in the same way as in rectangular waveguide. The numerical results exhibit that the modal birefringence of elliptical core PCF is at least one order of magnitude higher than the conventional elliptical polarization-maintaining fibers (PMF). Zero walkoff point occur at the longer wavelength than that of convention elliptical PMF. This can restrain the first order polarization mode dispersion. This fiber has a number of potential applications in polarization control and management.
