A High Sensitivity Plasmonic Structure by Using Electric and Magnetic Plasmon Modes
Source abstract
Abstract
A symmetric plasmonic nanostructure composed of two nanorods located along both sides of “I”-shaped structure is designed to produce Fano resonance, which resulted from the coherent coupling and interference between a broad bright mode and narrow dark mode. The broad bright mode stems from super-electric dipole oscillation of the two rods, while the narrow dark mode originates from the magnetic dipole plasmonic resonance induced by nearly circular current between the nanorod and “I”-shaped structure. By adjusting the length of a nanorod, double Fano resonances can easily be formed because of the symmetry breaking. Furthermore, it exhibits a larger modulation depth as well as tunability with varying length of the nanorod. The results show that a high refractive index sensitivity and figure of merit can be achieved in the near infrared by Fano resonance that appears in the designed structure, which make the designed configuration a good platform for applications in the fields of biochemical sensing and plasmon-induced transparency.
