Polymer nanocomposites with oxide and gold nanoparticles are known as suitable for efficient direct one-step optical relief recording [1-3]. We have further developed this type of light-sensitive materials by introducing additional nanoparticles like high-refractive index chalcogenide glass (ChGNP) as well as gold nanoparticles (GNP) and rear-earth oxides to the monomer/polymer matrix for upgrading the functionality of photopolymer . This way the average and spatially distributed refractive index, optical nonlinear parameters and luminescence of the processed nanocomposites were increased. At the same time the smooth adjusting of optical parameters after recording was realized due to the plasmon-resonance effects in GNP as well as reversible light-stimulated changes of optical parameters in ChGNPs. This way the amplitude-phase modulation characteristics of in-situ optically recorded photonic elements on the surface and in the bulk of thick composite layer on a given substrates were improved.
