Abstract

The influence of the fluorine-containing precursor type in the MCVD process on the size of soot particles is investigated by the method of laser ultramicroscope. The results of these measurements have shown that Freon-113 decreases the content of large soot particles, while SiF₄ does not. These results suggest an explanation of the optical loss reduction in highly GeO₂- or P₂O₅- doped single-mode fibers due to co-doping of the fiber core with fluorine.
