文摘The mechanisms of photoinduced microstructures in an azobenzene polymer film are presented.They are based on the spatial periodic modulation of optical intensity and the photoisomerization of azobenzene molecules with the movement of main chains.Experiment and theory jointly point out the possibility of photoinducing desired spatial microstructures in azobenzene organic polymer via adequate optical lattices and adequately polarized‘writing’beams.
