回顾了光纤通信的发展历史,从激光器的发明,到光纤的提出,再到掺铒光纤放大器(EDFA)的产生,如今光纤的铺设量已可环绕地球2 300圈,实现了全球范围内的光纤通信。但是随着人们对视频等信息的需求急速增加,网络流量爆炸式的增长使我们耗尽了可用的通信容量,所以急需新技术来增加通信容量。首先,重点介绍了光纤束和光子带隙光纤。然后通过分析光纤中损耗产生的机理,介绍了一种新的空气芯的HC-PBGF。这种光纤将通信波长移到中红外波长区,分析了这种特种光纤在传输链路中的各项性能指标。最后介绍了一种利用“激光泵浦激光”方法的新型高功率光纤激光器。

Recalling the history of the development of fiber-optical communication, due to the invention of laser, optical fiber and EDFA, optical fiber laid today can encircle the earth for 2 300 times, achieving a worldwide fiber-optical communication. But with the rapid increase in demand of information such as videos, the explosive growth of network has exhausted the available communication capacity, so there is an urgent need for new technologies in order to increase the communication capacity. First, Professor Payne highlighted the fiber bundle and the photonic band gap fiber. Then, by analyzing the mechanism of loss in fiber, he introduced a new air-core HC-PBGF(Hollow-core Photonic Band Gap Fiber), moving the communication wavelength to mid-infrared region, and he analyzed the performance of this special fiber. Finally, Professor Payne introduced a new high power fiber laser, using “laser pumps laser” method.
