| 摘 要： | 利用由速率方程、有限元场分布、传输方程构建的综合理论模型,数值求解了掺Er及Yb-Er共掺Al2O3光波导放大器的噪音系数和正反向自发辐射功率.结果表明,随波导长度的增加,当增益开始下降时,噪音系数显著增加.同时显示了抽运功率和掺杂浓度对噪音系数的影响,比较了两种掺杂放大器的噪音系数,Yb-Er共掺比只掺Er的约小0.8 dB.

| Abstract: | Noise characteristic of Er-doped and Yb-Er Co-doped Al2O3 waveguide amplifier (EDAWA and YEDAWA) are numerically calculated by multi theory model founded through rate equations,finite element field distribution,propagation equations.The influence of Er concentration,pump power and amplifier length on the noise figure is discussed.Forward and backward direction ASE power evolution along the propagation distance is also shown.The noise figure of YEDAWA is approximate 0.8 dB less than that of EDAWA. |
