Tellurium halide optical fibers

Abstract New infrared fibers, the TeX glass fibers, operating from 3 to 13 μm, have been developed. Tellurium halide based glasses have been optimized to produce low loss optical core-clad fibers in the 7–9.5 μm domain, and two drawing techniques are described. IR spectroscopy of organic species have been performed with core-clad fibers.
