Abstract

In this paper, we design a polarization splitter by combining a photonic crystal waveguide and internal polarization-selective rods leading to a spatial separation of two orthogonal polarizations for mid-infrared applications. The performance of the splitter is investigated by tuning the length of the polarization-selection rods or defect rods for both the polarization extinction ratio (PER) and degree of polarization (DoP). At optimized parameter of the selective rods, the DoP obtained a high value as 1 and the PER obtained a higher value greater than 30 dB for both TE- and TM-polarized lights.
