Abstract
We demonstrate volume gratings written in solgel-derived, Ge-doped silica m onoliths. Glass was fabricated both with and without germanium oxygen. defi cient center (GODC) defects. The UV absorption and UV-induced index changes of these glasses, with and without hydrogen loading, are reported. The pre sence of GODC defects greatly enhances the photosensitivity of Ge-doped sil ica with and without the presence of hydrogen. (C) 2000 Optical Society of America.
