Outline of Final Research Achievements

A theoretical analysis of the formation of photonic lattice structures in photopolymerizable nanoparticle-polymer composites (NPCs) under holographic
exposure was conducted. In quest for highly efficient volume holographic optical elements, we found that nanocomposite volume gratings recorded in NPCs dispersed with organic nanoparticles gave the refractive index modulation amplitude larger than 0.02. We also demonstrated coaxial holographic data page storage in thiol-ene NPCs dispersed with silica nanoparticles. Also, we developed NPC volume gratings dispersed with nanodiamonds for holographic control of slow neutron beams. In addition, we successfully observed high-order optical nonlinear responses due to the local-field effect in NPCs dispersed with semiconductor CdSe quantum dots.
