Both temperature and strain characterization of seed and regenerated gratings with and without post annealing is reported. The high temperature regeneration has significant impact on thermal characterization and mechanical strength of gratings while the post annealing has little effect. The observed difference is evidence of viscoelastic changes in glass structure.

Regeneration of fiber Bragg gratings under strain.
The effect of strain on both the index modulation, Δn(mod), and average index, Δ n, during grating regeneration within two types of fibers is studied and the observed Moiré interference cycling through regeneration indicates the presence of two gratings.
Ultra-high temperature chirped fiber Bragg gratings produced by gradient stretching of viscoelastic silica.

Fiber Bragg grating regeneration at 450°C for improved high temperature sensing.
Type-I fiber Bragg gratings photo-inscribed in hydrogen-loaded B/Ge co-doped silica single-mode optical fibers have been regenerated efficiently at 450°C, which is the lowest temperature reported so far and suggest the contribution of different mechanisms to the regeneration process with different relative dynamics.
