Photorefractive gratings in optical fibres
J.-L.Archambault, L.Reekie and P.St.J.Russell
Photorefractive fibre gratings are finding increasing use as quasi-distributed fibre strain and temperature sensors, filters in doped fibre amplifiers and narrowband feedback elements in tunable and single-frequency fibre lasers. These gratings can be fabricated routinely in a matter of minutes by exposing the core of a single-mode fibre to the interference pattern formed between two intersecting UV laser beams, and reflectivities in excess of 99% are now possible using this technique.
