Abstract
Photoinduced optical phenomena in silica fibers have received attention because of the demonstration of photoinduced second harmonic generation and photorefractive index gratings. For Ge doped fibers the mechanism responsible for both effects has been correlated with bleaching by UV irradiation of defects associated with the Ge ion. The effects of processing on UV bleaching of defects in high purity GeO2 have been examined. Bleaching kinetic studies indicate that processing variables such as melting temperature have a strong influence upon the bleaching of defects in GeO2 glasses.
