We studied the polarization properties of four photonic band gap fiber with elliptical core and different cladding geometries. To do so we relied on a fully vectorial calculation method, which uses a hybrid edge/nodal finite element approach with perfectly matched layer absorbing boundary conditions. We determined the spectral dependence of the confinement loss for the fundamental modes of orthogonal polarizations. Our results show that, for the four structures studied, the polarization dependent loss is so high that they can be used as fiber-optic polarizers in the ful band gap range.
