摘要：

A full scale numerical model for the erbium-doped fiber amplifier has been developed, incorporating realistic index and erbium-concentration profiles as well as the spectral distribution of amplified spontaneous emission. The high accuracy of the model is demonstrated by comparison with a comprehensive set of data, including gain, ASE, and pump power, obtained for a well characterized Er-Al-doped fiber. An absorption to emission cross section ratio of 1.0 was measured at the gain peak. Pumping at 654 nm, the excited state absorption was observed to be insignificant. A high gain of 39.6 dB was achieved in the experiment.
