174. Blazed surface relief formation in azobenzene-containing polymeric films by asymmetric polarization holography, N. Kawatsuki, E. Nishioka, A. Emoto, H. Ono and M. Kondo, Appl. Phys. Exp. 5 (2012) 041601.


New asymmetric polarization holography was carried out to achieve a blazed surface relief (SR) structure formation in a polymethacrylate film comprising 4-methoxyazobenzene side groups using asymmetrically controlled polarized 325 nm He-Cd laser beams. Asymmetrical molecular migration, which generated blazed SR structure of the film, was achieved by adjusting the influence of intensity and polarization distributions of the two beams on the molecular migration.
