Paper Abstract

Photofabrication of surface relief gratings on various polymer films containing azobenzene groups was demonstrated. Large surface modulation (greater than 6000 angstrom) and high diffraction efficiency (greater than 40%) could be obtained under optimal recording conditions. Formation of the surface gratings was observed in both organic and water-soluble azo polymers. We demonstrated the formation of various multiple gratings in a two dimensional format on the same spot by simply controlling the writing wavelength and the writing angle. The resulting surface pattern was a simple superposition of all the interference recording beams regardless of the sequence of the recording. Large surface grating could be created in the polymer film coated on various paper based flexible substrates.
