ABSTRACT:
A new photopolymerizable material allows single-step, fast recording of volume holograms with properties that can be electrically controlled. A method for preparing a switchable grating can comprise the steps of placing a mixture between a first and second slide, wherein the mixture has a photopolymerizable monomer, a second phase material, a photoinitiator dye, and a chain extender or cross-linker. The mixture is exposed to a laser and optical intensity pattern is applied to induce photopolymerization. A method for recording slanted reflection gratings can comprise the steps of placing a sample between a first and second glass prism, the sample comprising a polymerizable monomer, a liquid crystal, a chain-extending monomer, a coinitiator, and a photoinitiator. An incident light is split into two beams, wherein the beams enter the sample from opposite sides. The first and second prism are rotated to adjust the slant of the grating.
