Abstract
Disclosed is an optical waveguide fiber having a compressive outer layer that includes TiO,in the SiO,matrix glass. The compressive outer layer includes crystalline structures containing TiO,that are predominately rutile. Also disclosed is a method for making an optical waveguide fiber having a compressive outer layer. The compressive outer layer can contain an additional metal oxide that is preferentially lost from the outer layer, instead of the TiO,, during the drying and consolidation step.
