Title: Solution based approach for the fabrication of photonic devices in chalcogenide glasses

Abstract

In this report, we describe the solution preparation conditions of various chalcogenide glasses. The dissolution mechanism of (As{sub 2}S{sub 3}){sub 60}Ge{sub 40}, (As{sub 2}S{sub 3}){sub 60}Se{sub 40} in ethanolamine is studied. Dynamic light scattering (DLS)measurements confirms that the particles in suspension are <10 nm in all the solutions.Prepared solutions are shown to possess similar molecular structure to the parent bulk glasses. Optical properties of the prepared solution are also discussed.

  • Composite opal structures for nonlinear applications are obtained by infiltration with chalcogenide glasses As{sub 2}S{sub 3} and AsSe by precipitation from solution. Analysis of spatially resolved optical spectra reveals that the glass aggregates into submillimeter areas inside the opal. These areas exhibit large shifts in the optical stop bands by up to 80 nm, and by comparison with modelling are shown to have uniform glass filling factors of opal pores up to 40%. Characterization of the domain structure of the opals prior to infiltration by large area angle-resolved spectroscopy is an important step in the analysis of the properties ofmore » the infiltrated regions. {copyright} 2001 American Institute of Physics.« less
  • The exchange of silver ions between a solution and a cadmium-containing chalcogenide glass, which issued as a membrane in an ion-selective electrode, was studied by means of the {sup 110m}Ag radioactive isotope. It was shown that the exchange of silver ions increases with increase in temperature and with increase in the concentration of the solution containing labeled silver nitrate. The activation energy for the exchange of silver ions amounts to 0.27 eV. The concentration profiles of the {sup 110m}Ag were studied by sectioning the samples after exchange, and the diffusion coefficients of silver were calculated from a model of diffusionmore » from a source with a constant concentration. The activation energy of diffusion coincides with the activation energy of ionic conduction and is equal to 0.43 eV. Possible mechanisms of exchange at the glass-solution boundary are examined.« less
  • The exchange of cadmium ions between solutions and a cadmium-containing chalcogenide glass of the cadmium iodide-silver sulfide-arsenic sulfide system, which is used as a membrane in ion-selective electrodes, was studied by means of the radioactive {sup 115m}Cd isotope. It was shown that the exchange of cadmium ions obeys identical relationships both in the case of the labeled glass and in the case of the solution containing radioactive cadmium nitrate. The exchange of cadmium ions is proportional to the concentration of cadmium nitrate in the solution.
  • The nonlinear refractive index (n{sub 2}) of new germanium-based sulfo-selenide glasses has been measured at 1064 nm using Z-scan technique, with picosecond pulses emitted by a 10 Hz Q-switched mode-locked Nd:Yag laser. We have determined the impact of the progressive replacement of S by Se on the nonlinear properties of these glasses. The value of n{sub 2} strongly increases with the substitution of S by Se, up to 350 times the n{sub 2} for fused silica. X-ray photoelectron spectroscopy (XPS) indicates that the increase of Ge-Se bond units in the glass network is responsible for the increase of n{sub 2}.more » The suitability of these glasses for optical switching at telecommunication wavelengths based on such nonlinear properties has been also confirmed.« less
  • In this paper, we report results of n{sub 2} measurements of new chalcogenide glasses in the Ge-Sb-S-Se system using a modified Z-Scan technique. Measurements were made with picosecond pulses emitted by a 10 Hz Q-switched mode-locked Nd-YAG laser at 1064 nm under conditions suitable to characterize ultrafast nonlinearities. The nonlinear index increases up to 500 times the n{sub 2} of fused silica with an increase in the Ge/Se ratio and a decrease with an increase of the Ge/Sb ratio. We confirmed, using Raman spectroscopy, that the nonlinear refractive index depends on the number of Ge-S(Se) and Sb-S(Se) bonds in themore » glass network. Sulfide glasses were shown to have a nonlinear FOM near or <1, at 1064 nm. - Graphical abstract: In this paper, we report results of n{sub 2} measurements of new chalcogenide glasses in the Ge-Sb-S-Se system using a modified Z-Scan technique. n{sub 2} is found to increase with an increase of normalized photon energy, regardless of chalcogen type, but does not depend on the concentration of lone pair electron.« less
