Paper Abstract

In this paper, we propose a nanoscale plasmonic structure, which consists of a MIM bus waveguide coupled to a triple-cavity resonator system arranged in a T-shape. Numerical simulations by finite element method (FEM) and CMT are carried out to investigate the transmission spectra and field distribution of this special design. The results show that the PIA effect can be observed in the proposed structure with shoulder-coupling configuration. The group delay time at the center wavelength of PIA window can achieve to -0.232 ps using our proposed structure. We also dicuss the possible methods for controlling fast light characteristics. It is turn out that the PIA effect can be effectively controlled by varying the structural parameters of this plasmonic coupling system.
