Photodimerization of chromophores attached to a short peptide chain is investigated for high-capacity optical digital storage with UV lasers. The length and rigidity of the peptide chain assure an optimal distance and orientation of the chromophores for effective photodimerization. Using a theory developed by Tomlinson, the absorption cross section for the dimerization process in a uracil–ornithine-based hexamer is determined to be $9\times 10^{-20}$ cm2. A large change in the transmission due to irradiation in the UV area may make it possible to realize multilevel storage in a thin film of the peptides.
