Abstract

Surface plasmon resonance modes in a two-dimensional gold nanodisk array incorporated with super-lattice defects are investigated in this paper. Both transmission and absorption spectra of the super-lattice metal nanodisk array are calculated. The transmission spectrum exhibits an asymmetric Fano resonance lineshape and a narrow linewidth peak between two transmission dips. The electric field and polarization charge distributions at the transmission peak and dip wavelengths are also calculated. It is explained that the surface plasmon resonance modes associated with the large period nanodisks and small period nanodisks give rise to the Fano resonance lineshape and the anomalous transmission peak. We also retrieve the effective optical constants of the metal nanodisk array film. The effective optical constants exhibit strong chromatic dispersion and a small attenuation at the peak transmission wavelength. The strong dispersion and small attenuation can potentially be used for slow light.
