Bragg reflection gratings are holographically recorded in polymer-dispersed liquid crystal materials by using the 632.8-nm wavelength of the He-Ne laser. Mixtures of the commercially available E8 nematic liquid crystal, pentafunctional monomers, and photooxidant dye methylene blue are employed. We demonstrate that Bragg reflection gratings can be formed in this acrylate photopolymer system with reflection efficiencies of 52% with a peak notch at 1165 nm. We also present results for the switching characteristics of these gratings with switching fields on the order of 6 MV/m and rise times of 62 μs.
