Abstract :

A new method for calculating the gain of gamma irradiated Yttria- alumina silicate erbium doped fiber amplifier (GIEDFA) is purposed using a black box model (BBM) and compared with theoretical model at wavelength 1540 nm. Two important parameters which α and Pmax are introduced in (BBM) and are also almost independent of wavelength 1540 nm at the fixed radiation dose. Applying the BBM, we can estimate the gain in the wavelength of 1540 nm easily, only by the parameters of α, Pmax and the small-signal gain in corresponding wavelengths. The BBM gives a very good agreement results with the theoretical model, which affords a new way to characterize the gain deterioration characteristics of EDFA in radiation environment.
