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.
