Splet01. dec. 1984 · Using the PCVD method (plasma activated chemical vapour deposition), the incorporation of OH in optical fibres made of SiO 2 + GeO 2 has been studied. Impurities added to the gas phase (plasma) were CH 4, i-C 4 H 10 and H 2 O. The influence of F-doping by use of C 2 F 6 on the OH incorporation has also been investigated.
