UV irradiation influence on stimulated Brillouin scattering in photosensitive optical fibres

Abstract : A study on the influence of UV radiation on stimulated Brillouin scattering in photosensitive germanosilicate optical fibres is presented. The UV exposure of a highly germanium-doped fibre was performed at a power density of ~142 W/cm2. In this configuration, a refractive index change of about 2.5×10−3 was measured, partially due to the compaction phenomenon as well as a 20 MHz permanent change in the Brillouin frequency shift (at 1.55 µm).
