| 摘 要： | 研究了掺铒磷酸盐玻璃波导放大器的特性。利用重叠因子将980nm光抽运的掺铒玻璃波导放大器四能级模型的速率-传输方程进行化简，在考虑上转换效应和放大自发发射的情况下．利用数值模拟的方法，得到了掺铒玻璃波导放大器的增益与Er^3 离子浓度、抽运功率、波导长度等参量之间的关系曲线；同时模拟出放大自发发射曲线并与实验测量结果进行比较。结果表明在考虑上转换效应和放大自发发射的情况下,理论结果和实验测量结果是一致的。同时看到，选择合适的铒离子浓度是制作掺铒玻璃波导放大器的关键；并且为了全面发挥掺铒玻璃波导放大器的性能，需要抽运功率、波导长度等各个参量配合起来。

| Abstract: | Thecharacteristics of Er 3+-dopedphosphate glass waveguide amplifier (EDWA) are investigated. Using the overlapping factor, the rate-propagation equations of the four-level system of EDWA are simplified. With taking account of up-conversion and amplified spontaneous emission (ASE), the relation curves are obtained by numerical simulation between the gain and the parameters such as Er 3+ions concentration, pump power and waveguide length, and the theoretic results are consistent with the experimental results. Selecting suitable erbium ions concentration is the key of fabricating EDWA. Moreover, in order to improve the EDWA performance, the parameters are optimized such as pump power and waveguide length. |
