Abstract

The second part of the work consisted in simultaneously irradiating the manufactured ber Bragg gratings using a 60Co source of gamma-radiation. Spectral evolutions of all the gratings were collected during all the irradiation. Our results have shown that the saturation level of the Bragg wavelength shift is approximately the same for all the gratings re-coated with dffierent thicknesses of acrylate. The coating diameter therefore does not seem to influence the radiation sensitivity.
