Single-, two-, and multi-photon driven molecular motion and nanopatterning in azo-polymer films

Abstract: We review our work on nanopatterning in azo-polymer films by single, two-and multi-phopton driven molecular motion in solid bulk polymer. It is now known that light induced molecular movement occurs below the polymer glass transition temperature by chromophores photoisomerization via either linear or nonlinear absorption, and in this paper we will show that nanoscale polymer movement is induced by a tightly focused laser beam in an azo-polymer film just at the diffraction limit of light. The deformation patter… Show more
