本文对一种适用于模分复用的多模掺铒光纤放大器进行了数值模拟和实验研究。实验和数值计算结果表明，该掺铒光纤放大器能够以接近20 dB的增益均匀地放大LP11和LP21模。这种行为是通过调整纤芯内的铒空间分布来获得的。
We report on a numerical and experimental study of a multimode EDFA suitable for mode division multiplexing. This EDFA is designed to equally amplify LP11 and LP21 modes with a gain close to 20 dB, which is confirmed by experimental and numerical results. This behavior is obtained by tailoring the erbium spatial distribution within the fiber core.
