Thermal poling of glasses to fabricate masks for ion exchange

Thermal poling behavior and SHG stability in arsenic-germanium sulfide glasses

Second-order optical properties of thermally poled arsenicgermanium sulfide glasses have been investigated. Parallel studies of glass structure changes upon poling and/or visible cw-laser irradiation and complete SHG quantitative analysis have been performed. Key parameters and poling mechanisms influencing largely SHG stability and efficiency have been pointed out. ©2013 Optical Society of Ame...

Thermal Poling of Twin - hole Fibers

Thermal Poling of Twin-hole Fibers Jiawen Zhang Master of Applied Science Graduate Department of Electrical and Computer Engineering University of Toronto 2008 We developed a poling system that allows simultaneous inducing and characterizing second-order nonlinearity (SON) in fibers. The SON in fibers is induced via heating the fiber to an elevated temperature while applying an external voltage...

Trends in Effective Diffusion Coefficients for Ion-Exchange Strengthening of Soda-Lime-Silicate Glasses

Monovalent cations enable efficient ion-exchange processes due to their high mobility in silicate glasses. Numerous properties can be modified in this way, e.g., mechanical, optical, electrical, or chemical performance. In particular, alkali cation exchange has received significant attention, primarily with respect to introducing compressive stress into the surface region of a glass, which incr...

Optical and Thermal Properties of Mixed Alkali Phosphate Based Glasses

Glassy samples with a composition of 40P2O5&ndash;30V2O5&ndash;(30-x)Li2O&ndash; xK2O, 0<x<30 (mol %) were prepared by the conventional melt quenching technique in two forms of bulk and blown film. X-ray diffraction patterns corroborated the amorphous feature of the samples. Density of samples was investigated by using Archimedes principle. Based on absorption and reflection spectra, indirect a...
