Title: Optical waveguides mfr. - avoiding presence of trivalent titanium in deposited layer, thus preventing high attenuation
Inventor: LANGHEINRICH WERNER DR RER NAT
IPC: C23C16/453
Filed: 1974-04-27
Abstract: Optical waveguides mfr. in which a rod or tubular substrate is provided with a coating contg. >=1 constituents by flame hydrolysis and is then drawn into an optical fibre, is improved by dividing the flame hydrolysis into single, spatially-separate stages. In the pref. process, steam is generated in the flame of an oxyhydrogen burner and injected into a mixing chamber held at 100-300 degrees C together with other hydrolysable gases, but no hydrolysis occurs in this chamber; the gas mixt. then travels to the substrate which is heated to a higher temp. by a moving concentric furnace so that hydrolysis and therefore deposition occurs. Used for mfr. of optical fibres e.g. for communication transmission systems. Avoids attenuation in the fibres, esp. the high absorption losses due to the presence of trivalent titanium ions in the deposited layer.
