Abstract : The voids-fiber Bragg gratings (FBGs) are manufactured point by point by focalizing an infrared femtosecond laser in a small fraction of the core and creating a microscopic void. This makes these gratings very resistant and stable to high temperatures. However, until today, only very few tests under radiation have been performed on these FBGs. A complete study on the radiation response of this grating technology under X-rays is here presented, highlighting the dependence of its radiation response on dose, dose rate, irradiation temperature, and preirradiation treatment.
