Photosensitivity in tin-doped silica optical fibres
G.Brambilla, V.Pruneri, L.Reekie
Permanent gratings (refractive index modulation ~3 x 10−4) were written in tin-doped silica optical fibres with low levels of SnO2 (~0.15 mol %). In Ge-doped silica, ~10 mol% GeO2 is required to produce comparable photorefractivity under similar conditions.
