Paper Abstract

We demonstrate volume holographic recording in nanoparticle-polymer composites using thiol-ene monomers capable of step-growth polymerization by which shrinkage can be reduced as low as 0.2%. The reduced shrinkage is comparable to other low-shrinkage dry photopolymer systems such as those including a high content of inert binder components and using monomers capable of cationic ring-opening polymerization. It is shown that the thiol-ene based organic nanoparticle-polymer composites possess the refractive index modulation and the material sensitivity of 8×10-3 and 1014 cm/J, respectively, in the green, larger than the minimum acceptable values of 0.005 and 500 cm/J for holographic data storage.
