Tests of optical data storage in arrays of microfibers confirm its applicability and potential for higher storage densities than those achievable with conventional holographic data storage. Arrays of single-mode microfibers, spaced 0.78 µm apart and 60 µm long, were generated in a photopolymer film with four laser beams and simultaneously inscribed with Lippmann–Bragg fringes by use of a counterpropagating beam. Following the curing steps, spectra of white light retroreflected from a single fiber exhibit the reconstructed spectral lines of the multiwavelength laser used in the recording step; 1011 bits/cm2, or 1013 bits on a compact disk, appear to be recordable.
