© OSA 2016. Fiber Bragg grating regeneration involves the annealing and resurrection of a seed FBG through thermal annealing. Using micro-Raman and phase shift interferometry we reveal that the seed structure has changed the thermal history of the glass so that whilst the annealing is identical in all areas, the local glass relaxation is different and enhanced.
