我们从理论和数值上研究了一种低功率，超快，动态全光可调谐等离子体模拟电磁感应透明（EIT）在两个纳米盘谐振器侧耦合到金属-绝缘体-金属等离子体波导系统。利用等离子体激元类EIT效应的慢光效应和基于石墨烯-Ag复合材料结构的等离子体激元波导增强了光学克尔效应，具有巨大的有效克尔非线性系数。采用光学克尔效应调制方法提高调谐速率，响应时间可达亚皮秒甚至飞秒。通过动态调谐等离子体激元波导的传播相位，在具有低至5.85MW/cm（2）的强度的泵浦光的激发下实现了等离子体激元EIT类系统中的透射光谱的π相移。群时延控制在0.09 ~ 0.4ps之间。所有观察到的计划进行了严格的分析，通过时域有限差分模拟和耦合模式的形式主义。研究结果为光通信和量子信息处理中集成等离子体光子器件的低功耗和超快响应以及光器件的全光动态存储指明了新的方向。
We theoretically and numerically investigate a low-power, ultrafast, and dynamic all-optical tunable plasmonic analog to electromagnetically induced transparency (EIT) in two nanodisk resonators side-coupled to a metal-insulator-metal plasmonic waveguide system. The optical Kerr effect is enhanced by the slow light effect of the plasmonic EIT-like effect and the plasmonic waveguide based on graphene-Ag composite material structures with giant effective Kerr nonlinear coefficient. The optical Kerr effect modulation method is applied to improve tuning rate with response time of subpicoseconds or even femtoseconds. With dynamically tuning the propagation phase of the plasmonic waveguide, pi-phase shift of the transmission spectrum in the plasmonic EIT-like system is achieved under excitation of a pump light with an intensity as low as 5.85 MW/cm(2). The group delay is controlled between 0.09 and 0.4 ps. All observed schemes are analyzed rigorously through finite-difference time-domain simulations and coupled-mode formalism. Results show a new direction toward the low power consumption and ultrafast responses of integration plasmonic photonic devices and all-optical dynamical storage of light devices in optical communication and quantum information processing.
