ABSTRACT:
A process for producing a glass perform for optical transmission fibers, which includes supplying a gaseous silicon compound, ammonia or a gaseous nitrogen compound, and an oxygen-containing gas as starting gases into a high temperature zone to produce fine particles of SiOxNy glass and depositing the fine particles in the form of a soot or a transparent glass on a starting member to produce nitrogen-doped silica glass.
