Modeling and Experiments of the Gain and Noise Figure for an Irradiated Erbium-Ytterbium Co-Doped Fiber Amplifier
It is crucial to study the effect of radiation on the fiber amplifier
devices. In the present paper, the Erbium-ytterbium co-doped fiber amplifier
(EYDFA) has been irradiated by a neutron beam of different doses for various
exposure times from an Am-241/Be-9 neutron source. The gain and noise figure of
the EYDFA have been calculated theoretically and recorded after and before the
irradiation to test its performance under the effect of irradiation. In order
to show the enhancement in the gain of the fiber amplifier devices, a
comparison between the gain of the irradiated EYDFA and Erbium doped Fiber
amplifier (EDFA) has been carried out. The calculated results by the proposed
model are in good agreement with the experimental ones. It indicates that the
gain of EYDFA deteriorates after being irradiated by a neutron dose. Moreover,
the gain of irradiated EYDFA has been reduced to 13.8 dB at a dose of 720 Gy.
