中文摘要：

单层石墨烯是一种具有独特电学及光学特性的二维碳材料,尤其是在光学应用方面,它对可见光到近红外波段范围内光波仅有2.3%的线性吸收.由于石墨烯的独特性质,使得它可以作为一种具有超快响应时间以及超宽带工作特性的可饱和吸收体.本综述将展开石墨烯的线性及非线性光学特性分析,并重点阐述基于石墨烯可饱和吸收体的调Q及锁模光纤激光器研究进展,并指出厦门大学光电子技术研究所近几年来在这一方面所取得的成果.

英文摘要：

Single layer graphene is a 2D material which has remarkably electrical and optical properties. Especially, for the photonics applications, the absorption of single layer graphene is only 2.3 % range from visible to infrared light. The unique electrical and opti cal properties of graphene enable them acted as excellent saturable absorbers that has ultrafast response and ultra-broadband opera- tion. This review will highlight its linear and nonlinear optical properties. Then,we will present the overview and progress on current Q switched and mode-locked fiber lasers generated by graphene. The related achievements obtained by opto-eleetronics technology institute of Xiamen university in recent years will be specially emphasized as well.
