| Abstract: | 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 reviews 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. |
