Paper Abstract

TeX glass fibers with monoindex structure are routinely achieved with a minimum attenuation, less than 1dB/m, in the 8-12 micrometers strategic window. Their exceptional properties in the IR allow to investigate many potential applications such as laser power delivery, temperature sensing as well as remote chemical monitoring. Chalcohalide fibers having optical losses of 0.5dB/m between 7 and 9 micrometers have been obtained by the preform drawing technique. These optical fibers are generally protected with an appropriate coating, thermal and/or UV plastic. Such materials show clearly improved mechanical properties and a high flexibility suitable for industrial manipulations. A high sensitivity of TeX glass fibers for chemical analysis by remote evanescent wave spectroscopy has been demonstrated. The detection efficiency has been studied as a function of various parameters especially the fibers' diameter. TeX glass fibers with a tapered shape have allowed to detect very low concentrations of less than 1 percent vol. in ethanol.
