Abstract

In this paper we present a quantitative characterization of the effects of UV laser beam exposure in a new germanium doped photosensitive glass. Several samples (both bulk ones and containing waveguides) have been exposed under different conditions to UV laser beams produced both by a C frequency doubled Ar-ion laser and by a pulsed excimer laser. The measured characteristics allowed the estimation of photosensitivity properties for each case. We have then evaluated the thermal stability of the induced index variation measuring the samples kept at temperatures varying from 25 to 400 degrees Celsius.
