Formation of Nanostructures Upon Photoexcitation of Surface Plasmon Resonance in Nanocomposites Derived from Textured Gold Films and Chalcogenide Glass

Photosensitive plasmon-active structures derived from nanostructured gold films and chalcogenide glass As20Se80 have been prepared. Regular sub-wavelength reliefs are formed on the surface of As20Se80 glass due to the interaction of an amorphous chalcogenide glass film located on the metallic film nanostructures of different geometry and a localized near-field generated by photoexcitation of surface plasmon resonance in the gold films. The shape of the reliefs depends on the polarization of the laser light beam.
