New infrared fibers, the TeX glass fibers, operating from 3 to 13 mu m, have been developed. Tellurium halide based glasses have been optimized to produce low loss optical core-clad fibers in the 7-9.5 mu m domain, and two drawing techniques are described. IR spectroscopy of organic species have been performed with core-clad fibers. (C) 1998 Elsevier Science B.V. All rights reserved. [References: 11]
