ABSTRACT:
Optical fibers doped with nonglass forming refractory oxides, such as alumina and zirconia, are disclosed. Devitrification is retarded by adding an additional glass forming component, such as P.sub.2 O.sub.5, and by rapidly quenching the heated glass. Aluminum and zirconium-containing precursor vapors are formed by passing halide gas over heated aluminum or zirconium wire.
