摘　　要：石墨烯是一种有着独特电学和光学性质的二维材料,近年来在太赫兹波动态调制的研究中有着广泛的应用。本文主要对基于石墨烯的太赫兹波动态调制器件进行了综述,分析了电调制、光调制和光电混合调制3种调制方法的原理和优缺点,介绍了近几年来将石墨烯应用于太赫兹波动态调制所取得的一系列科研成果,着重对不同器件的调制性能进行了对比,分析了优势和不足。石墨烯可调超材料为实现更快速、高效的太赫兹调制器件提供了新的思路。Graphene is a two-dimensional material and has unique electrical and optical properties, which has been widely used in the research of terahertz wave dynamic modulation in recent years. In this paper, we re- views the terahertz wave dynamic modulation device based on graphene, analyze the principle and advantages and disadvantages of three kind of modulation methods such as electrical modulation, optical modulation and photoelectric hybrid modulation. We introduce a series of research achievements on the application of graphene in THz wave dynamic modulation in recent years, compare and analyze the advantages and disadvantages of the modulation performance of different devices. Graphene tunable metamaterial provides a new way to achieve more rapid and efficient terahertz modulator.
