Experimental results of the thermal regeneration of Bragg gratings recorded in hydrogen loaded high birefringence fibers are presented. The thermal characterization of saturated and non saturated recorded gratings is described, as well as results of the changes in the birefringence of these types of fibers when subjected to temperature variations.
