Abstract :
Loss spectra are compared in H2- and D2-loaded and gas-free N-doped fiber samples after γ-irradiation. It is found that D2-loading allows reduction of induced absorption at the wavelengths of 1.30 and 1.55 μm by a factor of ∼5 at a total dose of ∼1 MGy. H2-loading is shown to be less efficient, owing to H2 and OH-group absorption bands increasing the total loss in the telecom spectral windows. Pretreatment of fibers via D2-loading and pre-irradiation appears to be a promising radiation-hardening technique.
