Efficient recording of polarization gratings in dye-doped liquid crystals is reported. By exploiting the effect of light-induced anchoring of the molecular director, it has been possible to write stable holographic gratings with a diffraction efficiency of 8&percent; at a resolution of 1000 lines/mm. The required surface energy density of0.3 J/cm2sets these materials among the most sensitive for optical storage. ©1997 American Institute of Physics.
