Polymer films containing a donor-accepter type azobenzene moiety were prepared and formation of gratings based on a photoinduced change in refractive index was explored. When two linearly polarized beams of an Ar^+ laser (514 nm) were interfered in the CB30AB5 film (film thickness : 250 μm), the diffraction beam based on Bragg diffraction appeared immediately. The maximum diffraction efficiency reached 98% upon photoirradiation at 100 mW/cm^2 for 6 min. It was clearly observed that the response time became shorter with an increase in the light intensity of the writing beams, maintaining the high diffraction efficiency. Furthermore, holographic multiple data storages in the CB30AB5 film were demonstrated.
