“…Optical fiber based devices such as Fiber Bragg Grating (FBG) sensors have become highly attractive for nuclear, submarine, aerospace and space applications due to their resistance to electromagnetic interference, low density, mechanical flexibility, as well as great configurability [1][2][3][4][5][6][7][8][9][10]. A standard (type-I) FBG consists of a protective silica fiber cladding surrounding a photosensitive germanosilicate glass fiber core where periodic gratings are obtained by UV-inscription through a micrometric mask [11].…”

The effect of annealing cycle on regeneration efficiency was investigated through isothermal treatments between 700 and 1000°C. We determined an inverse relationship between the recovery rate of the peak reflectivity and temperature. A regeneration efficiency of 85.2% and long-term stability at 1000°C for 500 hours were achieved via a slow regeneration process. Thermal sensors developed by isothermal regeneration were determined to be reliable up to 1000°C (±2 °C). Experimental findings suggest the involvement of both diffusion related phenomena and stress variation through densification of the fiber core in type-I FBG during the thermal regeneration process.
