Abstract

An important issue of the UV-induced effects in germanium doped silica glasses is the long term stability. Investigations concerning the thermal stability show a major difference between effects induced by low and high intensity [1] (type I and type II). In this paper, the thermal response of UV-induced waveguides in germanium doped silica glass is investigated, as a function of UV-intensity.
