Paper Abstract

The plasmon-active mixed gratings were demonstrated and characterized in a volume holographic polymer nanocomposite. The counter-diffusion physical mechanism between the polymeric component and nanoparticles related to the holographic mixed gratings was analyzed. By dispersing gold nanoparticles in the bulk holographic polymer, a plasmon-active strong absorption grating was introduced into the polymeric refractive-index gratings. The nanocomposites with several volume ratios of doped gold nanoparticles were fabricated. Holographic angular selectivity curves of saturated diffraction efficiencies were measured for the prepared samples. Significantly suppression of side lobes with the improved diffraction efficiency was observed in the gold nanoparticles doped photopolymer. It is found that the noticeable holographic-apodization phenomenon is caused by the plasmon-active strong absorption grating.
