Abstract
The authors report on the use of magnetic fields in conjunction with m agnetostrictive materials for tuning and chirping optical fibre Bragg gratings. The Bragg wavelength shifts as a consequence of the strain i nduced in the fibre by a magnetostrictive rod when a magnetic field is applied. A tuning range of 1.1nm has been achieved by a magnetic fiel d of 103mT and the grating has been chirped by applying non-uniform ma gnetic fields.
