Paper Abstract

New Tellurium halide glasses denominated TeX glass have been investigated in the Te-Se-I and Te-Se-Br systems in order to qualify these vitreous materials versus their tendency to devitrify, the value of their glass temperature Tg and the position of the band gap absorption edge. While the multiphonon edge is located around 20 μm for all the glass compositions, it is noted that the band gap edge is very depending on the Se content. The first Tex glass fibers have been prepared from standard starting materials and it is verified that the lowest attenuation value around 5 dB/m is located in the 10-11 μm region.
