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.
