The paper is focused on the preparation and surface characterization of gold coatings and nanostructures deposited on glass substrate. Different approaches for the layer preparation were applied. The gold was deposited on the glass with (i) room temperature, (ii) glass heated to 300°C, and (iii) the room temperature-deposited glass which was consequently annealed to 300°C. The sheet resistance ...

indium tin oxide (ito) thin films were deposited on glass substrates by rf sputtering using an ito ceramic target (in2o3-sno2, 90-10 wt. %). after deposition, samples were annealed at different temperatures in vacuum furnace. the post vacuum annealing effects on the structural, optical and electrical properties of ito films were investigated. polycrystalline ito films have been analyzed in wide...

We demonstrate that direct femtosecond laser writing in silver-containing zinc and gallium phosphate glass enables generation of three-dimensional (3D) optical second-order nonlinear microstructures having an χ(2) value about 2.5 times that of quartz. The proposed physical model involves photo-reduction, photo-dissociation, and migration of silver species within the glass matrix. 3D laser-writt...

IN this outstanding 2"x2" Slide Projector, Bausch & Lomb has utilized the experience gained in manufacturing motion picture optical systems to give the user screen images of professional quality from black and white or color slides. Despite the exceptional brilliance of the screen images, slide temperature is kept within safe limits for all normal projection. The Bausch & Lomb 2"x2" Slide Proje...

Fluoride glasses are of great interest for optical applications, as low phonon energy hosts for rare-earth ions. With an increasing need for more compact optical devices that impose higher dopant concentration, research activity has been focused on the fabrication of fluoride glass planar waveguides to produce integrated lasers and optical amplifiers, especially those based on Er3þ-doped glasse...

Chalcogenide glasses from (GeSe2)100-x(Sb2Se3)x system were synthesized, with x varying from 5 to 70, in order to evaluate the influence of antimony selenide addition on nonlinear optical properties and photosensitivity. Nonlinear refractive index and two photon absorption coefficients were measured both at 1064 nm in picosecond regime using the Z-scan technique and at 1.55 μm in femtosecond re...

Some optical surfaces are formed by gravity sagging of molten glass. A glass sheet supported on a ceramic former is heated; the glass becomes a very viscous fluid and sags under its own weight until the lower surface is in full contact with the former. The smooth upper free surface is the required optical surface. Its shape is dependent on the initial geometry and, in optical terms, differs sig...

We report the optical studies of nanohole arrays in metallic coatings on cleaved optical fibers and also on glass substrates. Nanoholes are produced using electron-beam lithography and range in size from 100 to 700 nm; the pitch is varied from 300 to 3000 nm. Transmission properties are examined using visible 632.8 nm and infrared 1550 nm laser light. The observed interference patterns are dete...
