摘要
In this paper, we present detailed experimental analysis on the optical resonance transmission properties of nano-hole arrays in metallic films. Arrays of sub-wavelength holes with different periodicity (spacing between adjacent holes) in a square lattice arrangement were fabricated in optically thick metal films (Au, Ag, and Al) on a Pyrex substrate using Electron Beam Lithography. The optical transmission spectra of the nano-hole arrays were characterized in the visible and near infrared regime. The optical resonance transmission properties were observed to depend on the type of metal film and the periodicity in the lattice arrangement.
