Abstract

We present a two-photon-induced polarization-multiplexed and multilevel data storage method with a bis azobenzene copolymer film. A polarization-adjustable femtosecond pulsed laser is used as writing beam to induce anisotropy, and the recorded information is retrieved by a CCD sensor from the film with corresponding polarized illumination. It is found that the optical axis of bisazobenzene molecules can be reoriented under two-photon excitation by the polarized femtosecond laser via a photoisomerization process. Polarization-multiplexed and multilevel storage is demonstrated by using this method. The capability to combine both advantages of these distinct techniques makes it a novel approach to obtain higher optical data density.

Polarization-multiplexed storage in poly(MMA-co-M2BAN) film and the readout bit intensity as a function of the polarization direction of the reading beam. (a), (b), and (c) are three kinds of bit sequence in the same region read out by beams of different polarizations. (a) and (b) are recorded by 0°, 45° polarized laser beam and read out by 0°, 45° polarized illumination, respectively. (c) is read out by 22.5° polarized illumination. (d) The readout bit intensity as a function of the polarization direction of the reading beam. The circles are the experimental bit intensity, and the solid curve is the theoretical curve of cos ( 2 θ ) , where θ is the angle between the recording polarization and the reading polarization.
