Abstract: A method for controlling the refractive index achieved using a fluorine dopant gas, wherein CF4 is employed as the dopant gas, and the soot preform is doped using the CF4 for a time and temperature sufficient to result in a decrease in fluorine dopant nearest the surface which is in contact with the CF4 gas.

Abstract: A method for controlling the refractive index achieved using a fluorine dopa nt gas, wherein CF4 is employed as the dopant gas, and the soot preform (12) is doped using the CF4 for a time and temperature sufficient to result in a decrease in fluorine dopant nearest the surface which is in contact with the CF4 gas. Preform (12) is mounted on handle (11) which is fused to handle (14 ) and the assembly (20) is heated in a furnace muffle (15). The CF4 flows through furnace muffle (15), as indicated by arrows (17), and preferably contains a diluent gas such as helium. An optional centerflow gas (16) may b e flowed through the centerline hole (18) in several embodiments, which consis ts of helium. The end of the porous preform (12) may optionally include a capillary tube (19) to prevent the muffle gases (17) from entering the prefo rm.
