Paper Abstract

In this paper, the special property of polarization- splitting of groove phase gratings with subwavelength structures is investigated by mode-matching method. For suitable parameters such as period, groove depth and filling factor, the gratings are be high-reflective for TE polarization and antireflective (high-transmissive) for TM polarization. Two linear polarized normal incident lights of different wavelengths are split whether their polarization directions are perpendicular or parallel. For unpolarized monochromatic incident light, linear polarized lights are obtained in both reflection and transmission. Loss of energy is maximally avoided.
