Abstract: Optical waveguide core compositions comprising a core containing two dopants in a silica based glass, wherein one of the dopants is titania. The core composition serves to suppress the presence of Ti-3 and to preserve refractive index profile shape throughout the preform manufacturing process.

Abstract: A plurality of organometallic compounds (12-18) are converted into vapors and are mixed along with combustion gases (32-38) to form a vapor stream that flows along through pipe (40). This vapor stream burns at burner (42) to form soot (50). This soot (50) deposits onto rotating substrate (60) so as to form a consolidated oxide layer.

Abstract: The present invention is directed to a process for forming a preform suitable for consolidation to a glass blank for producing an optical waveguide fiber. The preform comprises a core portion and an inner cladding layer surrounding the core portion and contains SiO2 and TiO2. A portion of the TiO2 in the preform is in a crystalline form that is predominantly rutile. In addition to SiO2 and TiO2, the preform contains an additive compound that is preferentially sacrificed instead of TiO2 when the preform is consolidated. The process includes oxidizing Si and Ti containing compounds as well as a precursor of the additive compound to form SiO2, TiO2, and the additive compound. The preform containing these materials is then formed. In addition, the preform can be converted to a glass blank by consolidation of the preform.
