Experimental Investigation of Neutron Irradiation Effect on Silica-based Erbium-Doped Fiber Amplifier

摘要

This paper studied the influence of neutron irradiation on the characteristics of 980 nm pumped erbium-doped fiber amplifier(EDFA). After 7 days neutron irradiation, with the total fluence of 1.5×10~(13) n/cm~2, radiation induced loss changed little compared with pre-irradiation, maximum difference of single signal and WDM signal between pre-irradiation and post- irradiation are 0.5 dB and 0.6 dB, respectively. EDFA affected by neutron irradiation got less loss when the input signal power is higher.
