摘要：

A compact plasmonic system based on a stub metal-insulator-metal (MIM) waveguide coupled with a nanodisk resonator for plasmonic-induced transparency (PIT) has been proposed and numerically simulated by employing the finite-difference time-domain (FDTD). A reasonable analysis of the transmission features based on the temporal coupled-mode theory is given and is in good agreement with the FDTD simulation. In addition, the relationship between the transmission characteristics and the geometric parameters including the radius of the nanodisk, the coupling distance, and the deviation length between the stub and the nanodisk is studied in a step further. By optimum designing, the transmission of the PIT system can reach to as high as 90 %, as well as the group index can be over 88. The characteristics of our plasmonic system indicate an important potential application in integrated optical circuits such as optical storage, ultrafast plasmonic switch, highly performance filter and slow-light devices.
