Abstract
The properties of polarization holographic gratings formed in liquid crystal polymer composites doped with nonmesogenic nanoparticles (SiO2, ZnO, Al2O3, and Y2O3) are considered. The effect of these additives on the phase transition temperature of liquid crystals of polarization gratings, diffraction efficiency, and driving voltage is demonstrated.
