Abstract

The behavior of the concentration of photoinduced color centers in Ge-SiO2 optical fibers was compared with that of the index modulation associated with fiber Bragg gratings (FBG's) written in the same fibers. We find that the fluence dependence of the photoinduced Ge E center, its thermal annealing behavior, and its reaction with H2 are similar to that of the index modulation generated in both H2-loaded and unloaded Ge-SiO2 fibers. The much higher photosensitivity of H2-loaded Ge-SiO2 fibers is attributed to the much higher formation efficiency of Ge E centers, with an additional contribution from GeH. A diamagnetic structure, possibly densification, is also found to contribute to the index modulation of FBG's.
