This study describes the reorientation behavior of azobenzene containing polymer films by irradiation with non-polarized (NP) 365nm light and linearly polarized (LP) 633nm He-Ne lazer beams, and subsequent annealing. The irradiation with NP-365nm light generated Z-isomers. When this film is irradiated with LP- 633nm light, axis-selective Z-to-E photoisomerization occurred. After subsequently heating, high order orientation parallel to the electric vector of LP-633nm light was generated. Using this technique, polarization holography using, He-Ne laser was performed. The pure polarization grating with no surface relief grating formation was fabricated, and showed high diffraction efficiency (30% more) and thermal stability at room temperature.
