光子晶体光纤研究与应用

摘要

Photonic crystal fiber,a kind of microstructure or holey optical fibers,was a hot topic in the field of novel optical fibers in last twenty years.Because of its unique structure and optical properties,photonic crystal fiber attracted extensive attention for the application in fields outside optical communication.The fiber types, waveguide mechanism,preparation techniques,fiber characteristics and research progress were summarized. The applications of photonic crystal fiber in supercontinuum light source,fiber lasers,fiber sensors,etc.,were introduced.%光子晶体光纤是由光子晶体的概念发展而来的一类多孔微结构光纤，是近20年来新型光纤研究的热点。由于具有独特的结构和光学特性，光子晶体光纤在非通讯领域的应用受到广泛关注。对光子晶体光纤的分类、导光机制、制备工艺、光纤特性和研究进展作了综述，介绍了光子晶体光纤在超连续谱光源、光纤激光器、光纤传感器等方面的应用。
