中文拼音 [chāněrguāngxiān]
摻餌光纖
英文
edf erbium-doped fiber-
Edfa : erbium - doped fiber amplifier
摻餌光纖放大器Edfa erbium - doped fiber amplifier
摻餌光纖放大器Because power management in this thesis aims at amplified spontaneous emission noise of erbium ? oped fiber amplifier ( edfa ), the thesis introduces the simplified stark ? split energy levels of er3 ", amplified working mechanisms of er3 * and working performance of edfa in details
因為本文所採用的功率管理主要是針對edfa摻餌光纖放大器所產生的自發輻射噪聲去採取均衡措施，所以論文中詳細介紹了edfa中鉺離子的stark分裂的簡化的能級模型、鉺離子的放大工作機理及edfa的工作特性。The article includes six chapters : chapter one introduces the dwdm related concept, and the constitute of it. discuses the necessary of constructing the dwdm fiber transmission system, and brief describes the content of the article
第一章主要介紹了dwdm相關的基本概念，以及dwdm光纖通信系統的構成，論述了在光纜傳輸系統工程中採用dwdm技術的必要性，介紹了與dwdm技術密切相關的摻餌光纖放大器技術和光復用器件，並闡述了本文研究的主要內容。The methods and the experimental setups for measuring the gain and noise figure of an edfa are emphasized. we introduce how to measure the characteristics of each component of an edfa, especially the gain and absorption coefficient of an erbium doped fiber ( edf ). thirdly, four types of simple and novel l - band edfa structures with low noise, high gain and low gain ripple are proposed to satisfy the requirement of a dwdm system
基於考慮自發輻射噪聲（ ase ）的giles模型，建浙江大學博士學位論文立了這種edfa的全光增益箱制理論模型;理論和實驗分析了四種可能的光路結構、泵浦波長、光纖光柵反射波長和反射率、泵浦功率以及摻餌光纖長度等參t對其箱制特性的影響。The influence of the configuration, the pump wavelength, the bragg wavelength, the reflectivity, the pump power and the length of edf to the gain - clamped characteristics is studied. an optimal l - band gain - clamped edfa configuration with appropriate parameters of the amplifier, which can also provide a flat - gain band, are given
總之，本論文圍繞光纖通信領域的國際熱點問題，從理論和實驗上研究了高增益、低噪聲、譜平坦的摻餌光纖放大器的實現，關于edfa的特性的研究成果，我們相信能對科研生產起一定的指導作用。分享友人
