手性耦合纤芯(CCC)光纤作为一种新型光纤，具有单模传输稳定、熔接损耗低和便于紧凑盘绕等优点，为下一代高峰值功率和高能量的光纤激光器系统的发展提供了新的途径，逐渐引起国内外研究人员的关注。介绍了CCC光纤的结构、国内外最新研究进展和应用前景，同时简单阐述了该新型光纤的模式耦合相关原理。

Due to the robust single- mode performance, mode- distortion- free splicing and compact coiling, chirally-coupled core (CCC) fiber, as a novel fiber, has provided a new method for the development of the next generation high peak power and high energy fiber laser system and aroused wide public interest over the recent years. In this paper, we describe the chirally-coupled core fiber structure and mode coupling theory in this fiber. Recent development and some important applications about the novel fiber are also reviewed.
