Abstract

The optical effects were obtained by three different ways, which are opal structures, laser polymerizing and plasmonic ultrathin Ag films deposition. Opal structures were realized by deposition of a thin layer composed of sub-micron spheres of polystyrene on the surface of an optical fiber using drop-drying method and capillary method. Multiple diffraction gratings have been designed and obtained on mechanically processed optical fiber, through means of Two-Photon Polymerization via laser direct writing (3D Lithography - 3DL). Ultrathin Ag films of 1 to 9 nm thickness were deposited by RF Magnetron Sputtering onto different substrates.
