Optical properties of reflective liquid crystal polarization volume gratings

Polarization volume gratings are self-organized liquid crystal helical structures. They exhibit high diffraction efficiency and unique polarization selectivity. In this work, we investigate and compare two different configurations of polarization volume gratings: planar and slanted structures. We present the optical properties of polarization volume gratings with emphasis on their polarizing nature. Further experimental results reveal the existence of the slanted configuration.
