摘要
光纤放大器(OFA)是实现全光型光纤通信的关键性部件。因为它具有易集成、高增益、低噪声和带宽大的特点而得到广泛应用。近年来,随着人们对通信业务多元化的要求不断提高,信息和通信技术得到了飞速的发展,新技术的产生对光纤放大器的性能提出了更高的要求。在密集波分复用系统(Dense Waveguide Division Multiplex,DWDM)、有线电视网络(Community Antenna Television,CATV)以及光纤到户(Fiber To The Home,FTTH)大功率分配系统中,要求光纤放大器具有更高的饱和输出功率。掺铒光纤在经过短光纤时候不能提供更大的泵浦吸收,并且结构复杂、效率也低。铒镱共掺光纤是一个有效实现的方法。本文根据双包层光纤的结构特点,采用包层泵浦耦合技术,设计并搭建EDFA/EYDFA双段级联光纤放大器。
本论文深入研究了铒镱共掺双包层光纤放大器的基本理论,并使用仿真软件分析了铒镱共掺光纤放大器的基本放大特性:仿真实验重点模拟了光纤长度、泵浦光功率、信号光功率等对放大器增益的影响,分析了各种情况下的ASE分布,对进一步改善放大器性能提供了有力的理论依据。在理论的基础上设计并搭建了EDFA/EYDFA双段级联光纤放大器,并对其基本特性进行测试,实验中获得最高输出功率为1.85W,光-光转换效率21.5%,系统的总增益29.66dB。最后阐述了实验过程中发现的特殊现象并分析了其产生的原因。
Fiber Amplifier is one of the key components to realize all optical fiber communication system. Because it is easy to integrate, the high gain, the low noise and the band width major characteristic obtains the widespread application. In recent years, as people diversified communication services is ever increasing, information and communication technology has been rapid development of new technologies for optical fiber amplifiers having a higher performance requirements. In dense wavelength division multiplexing system (Dense Waveguide Division Multiplex, DWDM), cable network (Community Antenna Television, CATV) and fiber to the home (Fiber To The Home, FTTH) high-power distribution systems, fiber amplifiers have higher requirements saturated output power. Erbium-doped fiber amplifier can not provide adequate pump absorption via short fiber, the structure is very complex because of the long gain fiber, and the efficiency is very low. Doping Yb3+ in Erbium----doped fiber is an effective method. According to the double----clad fiber structure character and the packet layer pump coupling technique,I design and build EDFA/EYDFA two-stage cascade fiber amplifiers.
This paper study the basic theory of the Er/Yb co-doped double-clad fiber amplifier,and use of simulation software analysis of Er/Yb co-doped fiber amplifier amplification characteristics. The simulation study focused on an analysis of fiber length,pump power,signal power and other factors on the amplifier performance. And also analyzed the distribution of all cases of the ASE, to further improveing the amplifier performance provides a strong theoretical basis. Based on theory and designed and buildde the EDFA/EYDFA two-stage cascaded fiber amplifiers, And its basic properties were measured, The highest output power of 1.85W achieved in the experiment,which has an optic-optic efficiency of 21.5%.The total gain is 29.66 dB.Several particular phenomenon (Green light) found in the experiment is described and the causes of the phenomenon is analyzed.
