Abstract
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 microm apart and 60 microm 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; 10(11) bits/cm(2), or 10(13) bits on a compact disk, appear to be recordable.
