In this paper, a transmission‐type graphene plasmonic modulator by introducing off‐resonant Au structure is theoretically and experimentally investigated. It is found that the modulation efficiency and bandwidth could be dramatically enhanced compared with bare graphene plasmonic structure. The validity of this proposed method is verified both in the 1D and 2D graphene plasmonic structures: ribbons and holes. This work will open up a new path to design the high‐efficiency modulators, switches, and multispectral detectors.

基于石墨烯等离子体谐振器并结合非谐振Au结构的传输型光调制器

本文通过引入非共振Au结构对透射型石墨烯等离子体激元调制器进行了理论和实验研究。发现与裸石墨烯等离子体激元结构相比，调制效率和带宽可以显着提高。一维和二维石墨烯等离激元结构：带和孔都验证了该方法的有效性。这项工作将为设计高效调制器，开关和多光谱检测器开辟一条新途径。
