Paper Abstract

Multiple holographic gratings were recorded by 405nm laser in the same location of spirooxazine doped polymer films using peristrophic multiplexing techniques. Diffraction efficiency of each grating was controlled almost uniform by adjusting recording time. It was found that the growth rate of the holographic grating recorded later was lower than that of the earlier one, resulting from the decreased population of spirooxazine molecules. A kinetics description for the overlapped isomerization gratings agrees well with experimental results. Due to the thermal stability of the isomerization grating, multiple interference fringes in the photochromic film were reserved and observed by Confocal Laser Scanning Microscope.
