<p>PROCESS FOR THE GERMANIUM-DOPING OF OPTICAL WAVEGUIDE BASE MATERIAL BASED ON VITREOUS SILICA A process is provided which permits the effective manufacture of optical waveguide base material that has been doped with germanium and is based on vitreous silica. According to the invention, silicon chlorides of the formula SinCl2n+2, in which "n" is an integer from 2 to 6 especially hexachlorodisilane, are used as glass-formers in the presence of oxygen and germanium tetrachloride at temperatures of from 1100 - 1600.degree.C.</p> |
