Description/Abstract
Bragg gratings have been written in an optical fibre with a core
made of ternary SiO2:SnO2:Na2O glass and a SiO2 cladding. The
presence of Na2O allows for higher concentrations of SnO2
which is believed to be responsible for the photorefractive
response of this composition. In these preliminary experiments
significant refractive index modulations, up to 6.2x10-4, have been
achieved using a 248 nm excimer laser and a phase mask to write
gratings for reflectivity at around 1.5 µm. The induced refractive
index changes show enhanced temperature stability and there is
no sign of any erasure up to temperatures exceeding 600 °C.
