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 body made of carbon particles bonded together with a phenolic resin wherein the resin content is about 5% to about 35% by weight based on the total weight of carbon and resin. A method for making the body involves forming an aqueous mixture composed of in percent based on the total weight of the activated carbon and phenolic resin about 5% to about 35% solid phenolic resin, about 4% to about 10% plasticizing organic binder which can be cellulose ethers, cellulose ether derivatives, and combinations thereof, and the balance of the mixture being activated carbon particles, forming the mixture into a body, and drying the formed body.

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.

Abstract: The present invention is directed to low loss optical waveguides doped with tantala and methods of manufacturing such waveguides. SiO2 soot is doped wit h Ta2O5 to form a soot blank which is consolidated under conditions suitable t o prevent the crystallization within the Ta2O5-SiO2 containing waveguides. The resulting rod is then either drawn into an optical fiber or overclad and subequently drawn into an optical fiber. High temperature consolidation in either a gaseous atmosphere or vacuum atmosphere is used to sinter and vitri fy the soot blank prior to drawing to produce a low loss optical waveguide fibe r.
