Contribution of photoinduced densification to refractive-index modulation in Bragg gratings written in Ge-doped silica fibers

Research output › peer-review

Abstract

We have computed the contribution of UV-light-induced densification to the refractive-index modulation of fiber Bragg gratings. Our results confirm that, for strong gratings written in Ge-doped silica fibers with 248-nm UV light, density changes account for a major part of the photosensitivity effect.
