Chalcogenide-halide /C-H/ glasses for infrared optical fibers were studied, using compositions from the Ge-Se-I, As-Se-I and As-S-I systems, which exhibited good forming ability and thermal stability. By substituting I for Se, As-I or Ge-I bonds appeared, the concentration of As-Se or Ge-Se bonds decreased and intrinsic multiphonon absorption at 10 um was also diminished. The prepared glasses were characterized by lower Tg values; for fiber formation, a new method utilizing pumping glass melts into capillaries has been developed.
