Paper Abstract

Growing applications of optical fibers in remote sensing applications, such as evanescent wave spectroscopic monitoring of composite cure kinetics, has created a need for mid-IR fiber with the often incompatible properties of high glass transition temperature and high refractive index. A family of glasses in the Bi-Pb-Ga-Ge oxide system has been investigated for this application. The substitution of Ge into the base Bi-Pb-Ga ternary produces an increase in glass transition temperature and a decrease in refractive index, although the later remains high. Novel glass compositions having substantially higher stability than the base ternary are described.
