Abstract
An optical system that includes a cholesteric glassy liquid crystal film doped with a dye and configured to preferentially absorb light of a first handedness, such as left-hand circularly polarized (LCP) light, but pass light of the opposite handedness, such a right-hand circularly polarized (RCP) light. Adding an anti-reflection coating can further increase the transmission-to-reflection ratio.
