Spirooxazine could be used as optical storage medium due to the excellent photochromic characteristic. In this paper, dynamics of holographic grating recording in spirooxazine-doped PMMA polymers was investigated using two coherent green beams (532nm) and auxiliary blue-violet beam (405nm) of various powers. The diffraction efficiency and growth rate of holographic gratings as well as the production...
TiO 2 nanoporous films loaded with Ag nanoparticles exhibited distinctive photochromism and photoanisotropy under the visible linearly polarized irradiation. Based on such properties, a pure polarization holographic grating was recorded in the photochromic film using two orthogonal circularly polarized green beams (532nm) and reconstructed with a red beam (632.8nm). The diffraction efficiency...
