光子晶体光纤研究进展

Research advances of photonic crystal fiber

光子晶体光纤(PCF)由于具有传统光纤无法比拟的奇异特性,因而吸引了学术界和产业界的广泛关注,在短短的十几年内取得了很大的进展。本文从光子晶体的概念、光子晶体光纤的分类和导光机制开始讨论,分别阐述了全内反射型和光子带隙型光子晶体光纤的特性及应用,并且介绍了国内外的一些研究新进展。

Photonic crystal fibers （PCF） have attracted considerable interests because of their promising properties that are hardly achievable in conventional optical fibers, and a great development has been gained in the recent years. In this paper, the concept, class and transmission theory of PCF are firstly discussed, and then the basic properties and applications of total-internal reflection and photonic bandgap PCF are also presented. Meanwhile, some the latest advances of these fibers inside and outside are introduced.
