Abstract

A study was conducted to demonstrate the way microscale arrays of nanoholes can exhibit narrow resonance features in their transmission spectra, with a full width at half-maximum(FWHM). These structures, whose hole-hole spacings were found to be greater than the wavelength of incident light, showed significant spectral characteristics, as compared with subwavelength hole-arrays, due to high-order Bragg coupling. Angle-resolved transmission spectra displayed in the form of dispersion diagrams, confirmed the complexity of the zero-order transmission spectra that were found to meet the requirements of predicted models. Single-hole spectroscopic analysis also revealed that the polarization-dependent transmittance was dominated by surface plasmon polaritons (SPP) rather than localized surface plasmons (LSP) modes for anisotropic holes.
