Abstract A coupled-resonator structure consisting of a stub resonator and a nanodisk resonator is proposed and numerically investigated by using a two-dimensional finite element method. Simulation results show that two resonant modes occur in the transmission spectra, and the sharp and asymmetric Fano-lines increase with the wavelength resolution. We also analyze the properties of two resonant modes of the structure and design a similar structure supporting only one resonant mode, which has better wavelength resolution. Our models are important for improving the wavelength resolution in plasmonic devices and the sensitivity in sensors.
