    Abstract

    We report the photochemistry and development of a fluorescence readout-based, nonlinear absorption, three-dimensional optical data storage system In this system. writing was achieved by acid generation upon two-photon absorption (2PA) of a photoacid generator (PAG: at 7 10 or 730 nm) Readout was then performed by interrogating two-photon-absorbing dyes, after protonation, at 860 nm Linear and nonlinear photophysical characterizacion OF 2PA PAGs and acid-sensitive fluorescent dyes demonstrates good spectral resolution between the PAG and protonated 2PA dye and relatively high two-photon absorptivity Solution spectroscopic studies confirm photoacid generation and dye protonation Two-photon recording and readout of voxels were demonstrated in five and eight consecutive, crosstalk-free layers within a polymer matrix. generating a data storage capacity of up to 18 x 10(13) bits/cm(3)
