【摘要】Graphene has rich optical and electronic properties, nincluding zero band gap, high mobility and special optical absorption prop- erties, and it has attracted much attention. More and more investigations focus on its fundamental physical properties and electronic devices. However, many researchers believe that its true potential lies in photonics and optoelectronics, such as photodetectors, mod- ulators and transparent conductors used in light-emitting diodes or touch screens. In this review, we summarize its applications in semiconductor photoelectric devices, mainly for telecommunications.%石墨烯自从被发现以来，由于其零带隙、低电导率、常温下的高电子迁移率及量子霍尔效应和独特的光吸收等优良特性，引发了世界各国科研人员的重视，研究人员对其物理性质及应用的研究越来越多并且进展迅速．本文以光纤通信用光电器件中的探测器、调制器为主，综述了石墨烯在光电探测器、调制器以及超快锁模激光器和用于发光二级管、触摸屏透明导电薄膜等方面的应用．
