摘　　要：The tunable multiple plasmon-induced transparency （PIT） effect is investigated numerically in a metal-insulator-metal （MIM） waveguide with three side-coupled rectangular resonators. The system exhibits dual-mode PIT effects in the visible and near-infrared regions. By adjusting the geometrical parameters of the structure, we can manipulate not only each single PIT window, but also the double PIT windows simulta- neously. Our structures may have potential applications for optical communication, integrated optics, and optical information processing. The finite element method （FEM） illustrates our theoretical design.The tunable multiple plasmon-induced transparency （PIT） effect is investigated numerically in a metal-insulator-metal （MIM） waveguide with three side-coupled rectangular resonators.
