Paper Abstract

The polarization holographic gratings recorded in Au nanoparticles-doped methyl orange/polyvinylpyrrolidone (MO/PVP) composite films were investigated. The polarization state of diffraction beams was controlled by a probe light and holographic gratings together. The first-order diffraction efficiency of the MO/PVP film doped with Au nanoparticles was measured to be 3.2 times larger than that of pure composite film. Meanwhile, an obvious enhancement of photoinduced birefringence of MO molecules was also demonstrated. This enhancement of diffraction efficiency and photoinduced birefringence was discussed in terms of the localized field effect via the surface plasmon resonance of Au nanoparticles, which was confirmed by finite-difference time-domain simulation.
