- 18 - DOPED OPTICAL FIBER Abstract This invention relates to optical fibers at least the core of which contains at least 80 weight percent silica doped with nonglass forming refractory oxides, such as alumina and zirconia. Devitrification is retarded by adding an additional glass forming component, such as P2O5, 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.
