| 摘 要： | 在综合考虑Er^3 离子的能量上转换、交叉驰豫、激发态吸收效应以及光纤背景损耗后，依据所建立的均匀加宽四级结构速率方程组和光功率传输方程组，对碲基掺铒光纤放大器的增益特性进行了数值模拟，模拟结果与报道的实验测量结果达到了很好的一致。同时，对碲基掺铒光纤放大器的增益特性与输入信号功率、泵浦功率和光纤长度的关系进行了简要分析。

| Abstract: | Based on the rate equations and light propagation equations of homogeneously broadened four-level system, the numerical simulations for tellurite-based optical fiber amplifiers (EDTFA) are presented in the paper. Effects of energy transfer between Er3+ levels due to cooperative up-conversion, cross-relaxation, excited state absorption and background losses are considered here. The theoretical simulation results show a good agreement with the published experimental results. Further more, the relations between the amplifier gain and the input signal power, bi-directional pump power, and the fiber length are simulated numerically. |
