Abstract
We report on shift-multiplexed holographic storage of 250 digital data pages in a photopolymerizable nanoparticle–polymer composite film being capable of step-growth thiol-ene polymerization in the green. Various two-dimensional symbol modulation codes for the digital data page format were employed to examine the dependence of the readout fidelity on modulation coding schemes. It is found that, as compared to and modulation codes, higher-order , , and modulation codes possessing reduced white rates and higher coding efficiencies give lower symbol-error rates of and higher signal-to-noise ratios ().
