Abstract
We proposed and numerically investigate d a novel two dimensional (2D) photonic crystal (PhC) based polarization splitter. It
was demonstrated that by introducing single air hole defect into the PhC structure, a low cross talk polarizat ion splitter can be realized with significantly minimized reflection occurring at the interface between the dielectric material and air. For an
operating wavelength of 1.55 µm, an extinction ratio higher than 15 dB has been achieved in this study The low cross-talk feature together with the high tolerance of the variation in the size of the air hole arrays make the device proposed suitable for the integrated optical circuits..
