Circular Polarization and Wavelength Selective Gratings Based on Holographic Cholesteric Liquid Crystal Templates

Figure 2

Measured +1 order diffraction efficiencies of the refilled CLC template grating in (a)/(c) reflection mode and (b)/(d) transmission mode by the RCP and LCP lights with the wavelengths of 532 and 632 nm, respectively. The refilled material is RCLC-red in (a)/(b) and LCLC-red in (c)/(d).
