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.
我们已经计算了紫外光诱导致密化对光纤布拉格光栅折射率调制的贡献。我们的结果证实，对于用248纳米紫外光写入掺锗石英光纤中的强光栅，密度变化占光敏效应的主要部分。
