Erbium-Doped Fiber Amplifiers

该奖项将研究掺铒光纤放大器（EDFAs），该放大器已被公认为最近改变了光纤研究的进程。edfa已成为光波通信无可争议的冠军，许多专家认为edfa将彻底改变远距离光通信，从视频分发到宽带网络。一个新的时代确实已经出现在光纤界。所做的工作将巩固和进一步发展已经在NSF- SGER奖下完成的工作，其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，并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，并将重点放在800nm区域的抽运。其目的是最终实现低成本，非常可靠，性能优化和紧凑的EDFA模块，用于各种光波技术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，研究在1300 nm区域使用掺钕氟化物玻璃的理论放大器。

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.
