Abstract

We demonstrate the successful regeneration of optical fibre Bragg gratings that have been pressurized with helium instead of hydrogen. Helium-loading is performed after the inscription of the type-I seed grating. This work is of profound importance to the field of regeneration, confirming the existing theoretical model in which hydrogen plays a purely mechanical role in the regeneration process with no chemical reactions involved.
