Abstract
UV (248 nn) induced changes in the UV spectrum (165-300 nm) of optical fibre preform cores have been measured which can account for refracti ve index changes observed on writing Bragg gratings in optical fibres. The changes are thermally reversed at 900-degrees-C. A fibre grating has been thermally erased and rewritten with no significant change in fibre photosensitivity.
