Enhanced stability of the second-order optical nonlinearity in poled glasses
نویسندگان
چکیده
Glasses in a wide range of chemical composition were thermally poled and the stability of the second-order optical nonlinearity induced was studied through isothermal annealing experiments. Enhanced stability was found in aluminosilicate and aluminoborosilicate with respect to silica ~at least a five order of magnitude increase in lifetime!. Such dramatic enhancement was explained by the strong decrease of the alkali ion mobility due to specific changes in glass composition. © 2004 American Institute of Physics. @DOI: 10.1063/1.1760885#

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...
متن کاملDispersion and Nonlinearity in Ultra-Optical Ga2O3 and TiO2-Bi2O3-PbO Glass Systems
Dispersion, as the characteristic variation of refractive index with wavelength, is more pronounced, where the wavelength is approaching to the absorption band. In ultra-optical glasses, the nonlinear refractive index, concerning to the light intensity dependent phenomenon, becomes considerable. Here, two ultra-optical property glass systems; TiO2-Bi2O3-PbO (TBP...
متن کاملIdentifying the best chalcogenide glass compositions for the application in mid-infrared waveguides
We prepared numbers of GeAsSe glasses and investigated their thermal stability and optical properties in order to search the best glasses with relatively high glass transition temperature Tg, strong structural stability, low optical loss and high optical nonlinearity. Through our systematical measurements, we concluded that the glasses with a mean coordination number around 2.45-2.5 are the bes...
متن کاملEvaluation of Second Order Nonlinearity in Periodically Poled KTiOPO4 Crystal Using Boyd and Kleinman Theory
The effective nonlinearity ENL of periodically poled KTiOPO4 crystal is precisely measured with SHG experiment at various focusing conditions. The result shows the optimum focusing condition which maximizes the ENL at focusing parameter ξ at around 2.8 and is consistent with Boyd and Kleinman theory. The analysis based on the theory shows the nonlinear optical coefficient d33 of 17.5 [pm/V].

Ultra optical glasses are proposed for attaining noble glazes of high reflection and shine. In addition, these glasses can be used as semi-mirrors and optical instruments. In this reseach attempts were devoted mainly to introduce a glass system with the highest possible refractive index in which the highest reflection is desirable. Thus different amounts of heavy metal oxides modifiers, such as...
