Photopolymeric multifunctional dendrimer toward holographic applications

We present a photopolymeric multifunctional dendrimer for holographic applications. In this study, we described a synthesis of multiphotoreactive dendrimer and phase compatible polymer matrix as well as a numerical simulation of the dendrimer. This holographic photopolymer containing a nanosized photoreactive organic dendrimer could address the aggregation issue of conventional inorganic nanoparticle additives and allowed writing-induced shrinkage to be successfully reduced to the extent of acceptable values for 130 μm thick film. In this report, holographic performance including diffraction efficiency (DE), transmission, photosensitivity, modulation of refractive index, polarization sensitivity, and volume shrinkage has been discussed. The page-wise recording by using an amplitude spatial light modulator (SLM) was also demonstrated.
