Paper Abstract

Enhanced volume holographic refractive index grating by employing a strong volume holographic absorption grating induced by the periodic spatial distribution of gold nanoparticles due to the polymerization-driven multicomponent diffusion in a bulk gold nanoparticles doped photopolymer is noticeable. Till now most works are only focused on changing the concentration of nanoparticles and the radius of sphere nanoparticles. We propose an approach to improve the volume holographic grating by changing the size and shape of doped nanoparticles. The difference between nanorods and nanospheres is analyzed by the finite difference time domain(FDTD) method and the holographic kinetic model. The simulation results indicate that the nanorods has stronger localized surface plasmon resonance effect. The size and the aspect ratio of gold nanorods are optimized for the best absorption at a certain wavelength of recording light. The experiment results verify that the nanoparticles can be designed to achieve higher diffraction efficiency in a mixed volume holographic grating.
