摘要

使用數值分析建立模型找出鉺鐿摻雜光纖放大器的重要參數並且模擬光纖放大器特性。許多稀土光纖放大器的模擬非常複雜，需要眾多已知參數才能完成，而且無法一體適用，因此我們希望能夠建立一個通用於稀土光纖放大器的模型。此模型建立一套分析流程，只需取少量實驗數據就可以針對不同的光纖放大器進行特性分析。對於許多研究探討特定參數改變進而影響光纖放大器的變化，使用此模型可省去實驗冗長時間，快速得到答案，與實驗相互驗證，並且能最佳化實驗結果。

We have constructed a model, by using numerical analysis, to find several parameters of an Er/Yb co-doped fiber amplifier and to simulate the characteristics of the fiber amplifier. Many simulations of fiber amplifiers are so complex that they require the knowledge of many parameters of the fiber amplifier. For this reason, their usefulness is limited. In this thesis, we develop a general model for rare-earth ion-doped fiber amplifiers and establish an analytic process that can be used to analyze different fiber amplifiers by using only a few pieces of experimental data. When investigating how the performance of a fiber amplifier is influenced by varying a particular parameter, this model makes it possible to find the answer quickly, which can be verified with experimental results. We can also optimize the experimental results by using this model.
