Paper Abstract

We report the formation of strongly regenerated Bragg gratings in standard, telecommunications grade, fibre optics. The fibres are Hydrogen loaded for several days and the inscription of the seed grating is done using 248 nm UV light. Seed gratings are not fully saturated. When heated to 800 °C-1000 °C the seed grating is regenerated; and the new grating presents strong reflection spectrum.
