Abstract

We proposed an on-chip plasmonic anologue of electromagnetically induced transparency (EIT) with radiative and subradiant resonator side coupled to a metal-dielectric-metal(MDM) waveguide, theoretical and numerical simulation results show that this scheme can represent a three energy level EIT diagram in atomic system. A theoretical model based on coupled mode theory (CMT) is established to analyze the transmission spectrum of the structure, it agrees well with the FDTD result. The transparency peak can be achieved by adjusting the parameters of two resonators, and coupling strength can be adjusted by changing their gap width. The theoretical and simulation results can verify the PIT effects of resonator coupling based on surface plasmon polaritons (SPPs) and may provide a reference for highly integrated optical circuits.
