Abstract

Carefully prepared high silica optical fibers exhibit high initial strengths of 5 GPa but are susceptible to strength degradation with time by static fatigue.^1–3 Preliminary results have been reported⁴ on improved fatigue parameters obtained by employing a chemical vapor deposition reaction to protect the fiber with a thin, vitreous, amorphous silicon oxynitride We report here further results of this process, which allows fibers of arbitrary length to be coated with a silicon oxynitride film.
