Abstract

We demonstrate substantial shrinkage suppression of nanoparticle-polymer composite transmission gratings by use of the step-growth polymerization mechanism. It is shown that the polymerization shrinkage can be reduced as low as 0.3% at the nanoparticle concentration of 35 vol. % by which the refractive index modulation and the material sensitivity are maximized to be $8\times {10}^{-3}$ and 1014 cm/J, respectively, in the green. Our results offer a noticeable advance in the development of holographic data storage materials.
