A study of the preparation and properties of copper-containing optical planar glass waveguides

The Preparation and Characterization of Copper-Containing Thin Films Prepared by the Sol-Gel Method on Various Glasses

“…In order to exceed the emission of those substrates themselves, it is necessary to introduce a higher concentration of copper into the optical layer (as was observed for glass GIL49 and ion exchange in [5]). …”

“…Cu(0) nanoparticles introduce a ruby-red coloration of glass due to absorption with the maximum between 550 and 570 nm, a consequence of surface plasmon resonance, which gives such glass nonlinear optical properties [1][2][3][4]. Glasses containing copper in oxidation states, Cu(I) or Cu(II), create planar optical waveguides, which can be utilized in both passive (divalent copper) and active (monovalent copper) devices [5,6].…”

“…In this paper, we have developed this approach further and tested it on other types of silicate glasses. Besides microscope glass, we have chosen glasses BK7 and GIL49, which were previously used for the creation of optical layers by ion exchange [5,11] or ion implantation [12][13][14][15][16][17][18]. Thin films were deposited on these three substrates by the same approach as that used in [10], with the exception of using exclusively PEG-400 or Triton X-100 as surfactants as these had been proven to have the best effect on the adhesion of the layers to the substrates.…”

High-aluminum phosphate glasses for single-mode waveguide-typed red light source

“…The trivalent rare-earth ions incorporated phosphate glasses are a promising candidate to develop optical devices because of their significant properties, i.e., high thermal expansion coefficient, ultraviolet transmission, suitable refractive index, less dispersion and low melting temperature. Moreover, phosphate glasses represent high rareearth ions solubility, good chemical stability and excellent ion exchangeability, which allow high concentration doping without significant non-radiative relaxation and are attractive to fabricate high efficiency waveguides that can meet the demand of highpower and compact laser cavity [10][11][12][13][14][15][16][17][18][19]. With the addition of Al 2 O 3 , the thermal and chemical stability of phosphate glasses will be largely improved [20][21][22][23][24][25] for stable requirements in wet chemical etching and ion-exchange process during waveguide fabrication.…”

Formation of luminescent optical waveguides in silicate glass matrix by the ion-exchange technique

“…Спектры люминесценции также структурированы и содержат две полосы -одну с максимумом вблизи 430 нм и вторую, более ши-рокую, с максимумом вблизи 510 нм. В люминесценцию в спектральном интервале 460-550 нм вносят вклад, в основном, ионы Cu + [28,29]. Данным люминесцентным центрам соответствует полоса возбуж-дения с максимумом на длине волны 300 нм.…”
