摘　　要：自2004年被发现以来,石墨烯因其卓越的光学和电学性能及其与硅基半导体工艺的兼容性,备受学术界和工业界的广泛关注。作为一种独特的二维原子晶体薄膜材料,石墨烯有着优异的机械性能、超高的热导率和载流子迁移率、超宽带的光学响应谱及极强的非线性光学特性,使其在新型光学和光电器件领域具有得天独厚的优势。一系列基于石墨烯的新型光电器件先后被研制出,已显示出优异的性能和良好的应用前景。此外,近期石墨烯表面等离子体激元的发现及太赫兹器件的研究进一步促进了石墨烯基光电器件的蓬勃发展。综述重点总结近年来石墨烯在超快脉冲激光器、光调制器、光探测器以及表面等离子体领域的应用研究进展,并进一步分析目前所面临的主要问题、挑战及其发展趋势。Graphene has very significant optical and electronic properties, which attract enormous attention. As a unique two-di-mensional crystal with one atom thickness, it has high electron and thermal conductivities in addition to ？ exibility, robustness and impermeability to gases. Its ultra-broad band optical response and excellent non-linear optical properties make it a wonderful material for developing next generation photonic and optoelectronic devices. The fabrication of graphene-based devices is compatible with the existing semiconductor process, which has stimulated lots of graphene-based hybrid silicon-CMOS （ Complementary metal-oxide-semiconductor transistor） applications. Here we review the latest progress in graphene-based photonic and optoelectronic devices, ranging from pulsed lasers, modulators and photodetectors to optical sensors. Other exciting topics such as graphene surface plas-mons and their terahertz applications are also discussed.
