Herein we report an interpenetrating network (IPN) photopolymer containing an inorganic hyper-branched photoreactive polyhedral oligomeric silsesquioane (POSS) nanoparticle (NP) which can address the problem of light scattering induced by the aggregation of nanoparticles and can allow writing-induced shrinkage to be successfully reduced to the extent of negligible values for 500-μm-thick film. Holographic optical properties including diffraction efficiency (DE), sensitivity, and volume shrinkage are investigated as a function of POSS concentration. Angle multiplexing and page-wise recording are also demonstrated by using an amplitude spatial light modulator (SLM).

Keywords:volume gratings;holography;polyhedral oligomeric silsesquioane (POSS);interpenetrating network (IPN);epoxy.
