    Abstract

    A novel sub-wavelength metal-insulator-metal (MIM) type electromagnetically induced transparency (EIT) system based on metal surface plasmon polaritons (SPPs) is designed. It is composed of a straight waveguide coupled with symmetrical stub cavities and nanodisks. The structure is analyzed by the coupling mode theory and numerical simulation is carried out with the finite-difference time-domain (FDTD) method. When the resonant frequencies of the stub cavities and nanodisks are about the same, EIT-like effect can be obtained. The position of transparent window can be adjusted by changing the stub cavity length and radii of the nanodisks. The device can be used as a high performance EIT-like filter with transmission rate up to 77.5%, full width at half-maximum (FWHM) less than 35.5 nm and group index over 65. The system provides a new method for the highly integrated optical networks. It can be applied to wavelength selector, ultrafast switching, optical storage and other devices.
