【正文】 n be optically amplified in the full band of 1670 nm to 1270 nm. This paper introduced the history and current situation of the FRA, the basic principle of Raman scattering, and the working principle of Raman fiber amplifier. And its system structure, including the gain medium, pump source and passive ponents are introduced. On the basis of the working principle, the paper analyses its characteristics, including the gain, noise, polarization dependence, temperature, etc. According to the basic theory of the understanding, it is used optisystem software to optimize simulation. For optimize simulation, the paper is done by array pump39。 stimulated Raman scattering。 array pump目 錄論文總頁數(shù)：27 頁1 引言 ..............................................................................................................................................12 概述 ..............................................................................................................................................1 拉曼光纖放大器主要應(yīng)用 ...................................................................................................1 拉曼光纖放大器的研究方向 ...............................................................................................1 拉曼光纖放大器的發(fā)展 .......................................................................................................23 拉曼光纖放大器的原理 ..............................................................................................................2 拉曼光纖放大器的組成 .......................................................................................................2 拉曼光纖放大器的分類 .......................................................................................................4 拉曼光纖放大器的原理 .......................................................................................................5 受激拉曼散射 ................................................................................................................5 拉曼光纖放大器的拉曼增益 ........................................................................................6 拉曼光纖放大器的拉曼閾值 ........................................................................................7 拉曼光纖放大器的特性 ................................................................................................84 拉曼光纖放大器的優(yōu)化仿真 ....................................................................................................10 陣列泵浦模型的建立 .........................................................................................................10 對泵浦功率的優(yōu)化 .............................................................................................................12 對泵浦波長的優(yōu)化 .............................................................................................................17 對光纖有效作用面積的優(yōu)化 .............................................................................................19 對光纖長度的優(yōu)化 .............................................................................................................21結(jié) 論 ..........................................................................................................................................24參考文獻(xiàn) ..........................................................................................................................................24致 謝 ..........................................................................................................................................26聲 明 ..........................................................................................................................................27第 1 頁 共 27 頁1 引言光纖放大器是的原理在光纖的纖芯中摻入能產(chǎn)生光子的稀土元素,比如鉺、鐠、銩等，這樣
