Abstract

Light-induced anchoring of the molecular director is reported to be an efficient method for writing permanent holographic gratings in dye-doped liquid crystals. We have achieved higher sensitivity and spatial resolution in these materials with other methods. An energy density as low as ${10}^{-1} \mathrm{J}/{\mathrm{cm}}^2$ was sufficient to write gratings with a resolution higher than 100 lines/mm.
