Polarization holographic gratings in sp configuration are written at 488 nm in photorefractive organic–inorganic films based on SiO2 . The films, prepared by a solgel technique, contain Disperse Red 1, carbazole units, and 2, 4, 7-trinitro-9-fluorenone. The gratings are characterized by their diffraction efficiency for a 632.8-nm probe. The polarization gratings act as a half-wave plate, and the diffraction efficiency is independent of the polarization direction of the probe.
