Abstract
Optical fibers having high infrared transmittancies are produced by chemical vapor deposition of vitreous layers composed predominantly of anions S, Se and/or Te onto tubes or rods. Cations are Ge, Si, P, B, As, Sb and/or Ti. Conventional CVD techniques are employed to produce stepped-refractive index gradient profiles in the fibers except that an inert gas and/or a halogen(s) is used as the propellant gas.
