Erbium-Doped Fiber Amplifiers

该奖项将调查掺铒光纤放大器(EDFA)，它们最近已经被认为改变了光纤研究的进程。EDFA已成为无可争议的光波通信冠军，许多专家认为，EDFA将彻底改变从视频分配到宽带联网的长距离光通信。一个新的时代确实已经开始在光纤社区出现。所做的工作将巩固和进一步发展在NSF-SGER奖下已经完成的工作，在该奖项中，开发了一个全面的理论计算机模型。该模型可以非常准确地预测任何类型的EDFA的性能，这与已发表的实验结果非常吻合。将进行理论和实验研究工作，并将集中在800 nm区域的泵浦。这旨在最终实现低成本、非常可靠、性能优化和紧凑的EDFA模块，用于光波技术中的各种应用中的功率放大器、线路中继器和前置放大器。EDFA为开发完全透明的网络提供了令人兴奋的可能性。通过考虑优化的光纤设计和不同的泵浦配置，还应从理论上研究掺钕氟化物玻璃1300 nm区域的放大器。

This award will investigate erbium-doped fiber amplifiers (EDFAs), already recognized as having changed the course of fiber optics research recently. EDFAs have emerged as the undisputed champion lightwave communications, and many experts believe that EDFAs will revolutionize long-distance optical communications, from video distribution to broadband networking. A new era has indeed dawned upon the fiber optics community. The work done will consolidate, and develop further, the work already done under a NSF- SGER award, in which a comprehensive theoretical computer model was developed. the model can predict the performance of any type of EDFA very accurately, as evidenced by the excellent agreement with published experimental results. Both theoretical and experimental research work will be done and shall concentrate on pumping in the 800 nm region. This is aimed at the eventual realization of low cost, very reliable, performance optimized and compact EDFA modules for use as power amplifiers, line repeaters and preamplifiers in a variety of application in lightwave technology. EDFAs offer the exciting possibility of developing completely transparent networks. The shall also investigate theoretically amplifiers for the 1300 nm region with neodymium doped fluoride glass, by considering optimized fiber design and different pumping configurations.
