AB - We demonstrate the efficient inscription of Bragg gratings in a few-mode Bi and Er doped complex germanosilicate ring-core fibre also containing P and Al. The thermo-optic properties and thermal stability of these gratings are presented and the potential for sensing applications are discussed. © 2012 SPIE.
