Abstract :
In-fiber Bragg and long-period gratings as well as Mach-Zehnder interferometers based on germanium- and nitrogen-doped silica fibers have been investigated under γ-rays. The majority of the experimental results suggest that both types of gratings in both types of fibers are stable with respect to γ-ray doses of up to 1.47 MGy
