Paper Abstract

A new class of far I.R. transmitting glasses has been discovered in the following systems : Te-CI, Te-Br, Te-CI-S, Te-Br-S, Te-l-S, Te-CI-Se, Te-Br-Se, Ted-Se. The ternary glasses are in general very stable against devitrification and moisture. Many of them show very interesting optical properties and potential low losses in the atmospheric window 8-12 μm. Consequently, they can find many applications in thermal imaging, delivery of 10.6 μm emission of CO2 laser etc... These glasses could be used in form of thin films. Vitreous thin films with controlled composition and so with controlled refractive index have been obtained by sputtering. Planar wave guiding structure could be realized without difficulty. The fiber drawing is being in progress and the preliminary results lead to optical losses around 5 dB/m at 10.6 μm for a single fiber. This attenuation can be compared with the best existing glass fibers.
