Recent improvements in the development of IR TeX glass fibers

Tellurium Iodide based glass fiber preparation has been optimized in order to respond to several IR waveguide technological demands. Three directions have been examined: 1) realization of a two fiber systems for radiometry in the room temperature range, 2) chemical polishing of a core-clad fiber for evanescent wave remote IR spectroscopy, 3) attempts for single mode fiber operating in the 10 μm region for planetary spectroscopy.
