光学介质谐振腔中的类电磁诱导透明（EIT-like）效应在慢光调节、超快光开关、量子存储等领域具有广泛应用。利用石墨烯超材料的结构特性、强局域特性和高载流子迁移特性不仅可以获得更显著的EIT-like现象，而且可以实现光的速度和光谱特性动态调控，继而设计出纳米尺度可调谐超快光电子器件。本项目计划：.（1）利用空间耦合波模型，研究对称/非对称石墨烯超材料结构中EIT-like的产生机理及结构对称偏移量、石墨烯电导率等对效应产生的影响。（2）设计易于产生和调制EIT-like的基于超材料的新结构，如层叠排列结构。（3）分析新结构在调制下产生的慢光控制、超快光响应等物理特性。（4）研发基于以上结构和特性的折射率传感器、太赫兹波段滤波器、光子逻辑器等超快新器件。.本项目意在探索光子调控的机理，揭示人工材料的新特性，开发性能优异的新器件，为下一步新型微纳光子器件开发打下良好基础。

Electromagnetically induced transparency(EIT) as a thrilling and counterintuitive phenomenon has received much attention due to its interesting physics and potential applications such as the transfer of quantum correlations and slow light propagation in nanoscale devices. The concept of EIT later extended to classical optical systems by using plasmonic metamaterials, due to the unique optical properties of EIT-like in metamaterials result from interaction and coupling of light with periodic particle. .Optical control of EIT-like in metamaterials promises essential application opportunities in optical networks in recent years . The specific geometry and arrangement of nano-scale inclusions in metamaterials can result in enhanced plasmon resonance, especially the localized surface plasmon resonance or surface plasmon polariton (SPP) resonance, which is one of essential conditions for realizing high transmission EIT-like resonance..Graphene, an attractive carbon material, becomes a hot material in both physics and engineering on account of its exotic properties, such as optical transparency, flexibility, high electron mobility. Graphene-based plasmonic nanostructures provide smaller losses and highly confined plasmonic modes that can be tuned synchronously and locally via chemical doping or electrical gating. These make graphene is recognized as an excellent candidate for designing tunable, fast, and compact active plasmonic devices. .In this project, we proposed active plasmonic device based on doped graphene metamaterial. Expect to find that (1) an increase of the Fermi energy level can result in a significant shift of outcoming light property without changing the structure of the device;(2) new mechanisms for producing EIT-like effect; (3) fantastic characteristics for the propagation of electromagnetic waves in plasmotic structure; (4)new category of photonic device. .It may be helpful for the designing of new functional nano-photonic devices and may pave the way towards ultrafast active graphene-based plasmonic devices.
