Abstract

We demonstrate shift-multiplexed holographic storage of 180 digital data pages with low symbol-error rates in a thick (250 μm) SiO2 nanoparticle–polymer composite film using step-growth thiol–ene photopolymerization. A two-dimensional 24 modulation code was employed for formatting digital data pages in order to reduce the average intensity of code block without decreasing the coding efficiency. This study clearly shows the feasibility of the thiol–ene based nanoparticle–polymer composite system as a holographic data storage medium.
