Photorefractive index gratings in SnO<sub>2</sub>:SiO<sub>2</sub> optical fibres

Permanent photorefractive gratings with considerable refractive index modulations (~3×10<sup>-4</sup>) were written in silica optical fibers doped with very low levels of SnO<sub>2</sub>(~0.15 mol %) using ultraviolet (UV) laser radiation at 248 nm. The photoinduced refractiv...
