Abstract

Electrically switched holographic composites (ESHC) based on Polaroid photopolymer materials were described previously using optically generated holograms. These techniques have now been extended to include computer generated holograms. A highly accurate laser writing engine was utilized to write multi-phase level diffractive gratings in Polaroid type DMP-128 photopolymer film. After compositing with liquid crystals and applying an electric field, the diffraction efficiency of the elements could be switched or tuned continuously over approximately a 100:1 range of diffraction efficiencies, opening a new range of interconnect applications.
