Teo2-Based Glasses: Properties And Structure

Much attention has been focused on tellurite glasses for practical applications such as optical modulators and memories in the shape of bulk or under fibre waveguide form. These glasses have a low melting temperature, high refractive index, and high transmission in the infrared region to 5mm. In addition, TeO2-based glasses exhibit the highest nonlinear refractive index n2 ever found for oxide glasses. In order to find a correlation between the physical properties of these glasses and their atomic arrangement, structural characterisations were done.
