  • Title: Poled polymer thin-film gratings studied with far-field optical diffraction and second-harmonic near-field microscopy.
    Author: Schaller RD, Saykally RJ, Shen YR, Lagugné-Labarthet F.
    Journal: Opt Lett; 2003 Aug 01; 28(15):1296-8. PubMed ID: 12906068.
    Abstract:
    Electrical poling induces polar ordering of molecules in a grating that has been holographically inscribed on a thin film of polymer with azobenzene side chains. The resulting chi2 grating, seen by second-harmonic-generation (SHG) near-field scanning optical microscopy, can have a periodic structure that is significantly different from the topographical image. The far-field linear and SHG diffration patterns correlate well with the grating structures. Poling of the thin-film grating, which presumably has photodriven nonuniform material properties within each period, leads to the more complex structure of the chi2 grating.
