This study demonstrates a switchable transflective polarization grating based on cholesteric liquid crystals (CLCs). The planar and uniformly lying helix (ULH) states of CLCs allow for the reflective and transmissive modes of the polarization grating, respectively, and either state can be switched to the other by applying low-frequency pulse voltages.
