Abstract
Effects of UV-dose and fiber strain on annealing properties of fiber gratings written in Ge-doped fibers have been experimentally investigated. It was found that tensile stress in the fiber core strongly changes the grating decay curve. A new band in the distribution of the activation energy of the grating thermal decay with a center at 2.9 eV has been observed.
