Ag-doping in chalcogenide glasses can significantly increase the material's optical nonlinearity. This paper describes our study on Ag-doped As2Se3 glasses. The effect of Ag doping on the glass structure and optical properties have been discussed.
In this study GeXAsySe100x+y glasses with 0lesx<40 and 12lesy40 are characterized to determine the effects of varying composition on parameters such as the nonlinear refractive index (n2), glass transition temperature (Tg) and the optical absorption band edge (Eg). The linear absorption losses were studied using photo-thermal deflection spectroscopy (PDS). We found that increasing the Ge concentration...
GexAsySe100-x-y glasses with 0les xles40 and 12lesyles40 have been characterized for properties of bulk material as well as thermally deposited films. The effect of phase separation on film properties is studied.
