Paper Abstract

We report on the volume holographic grating formation in photopolymerizable polymer nanocomposites that incorporate new hyperbranched polymers (HBPs) acting as transporting organic nanoparticles. Since HBPs are easily dispersed to acrylate monomer without any aggregation and possesses ultrahigh index of refraction of the order of 1.8 in the green due to the inclusion of triazine and aromatic ring units, volume gratings with good optical quality and refractive index changes as large as 2.2 × 10−2 can be recorded. It is also shown that the out-of-plane thickness change due to polymerization shrinkage is reduced to 2% or lower by the HBP dispersion.
