Abstract
Complementary layer pairs consisting of an array of elongated gold patches on one layer with the complementary elongated holes on a second separated gold layer were fabricated by laser interference lithography using a double-exposure method. The anisotropic complementary layers, with a stretched hexagonal lattice, show polarization dependent enhanced transmittance at near-infrared wavelengths. The wavelengths of the peak transmittance through the plasmonic films are well correlated with the wavelengths of the resonant excitations of surface plasmon resonances of the system. The enhanced transmittance through such complementary layer pairs and the role played by the plasmonic resonances at the wavelengths with peak transmittance are confirmed through electromagnetic simulations. The enhanced transmittance is mediated by the plasmonic resonances of the hole arrays or cavity resonances due to the pair of complementary layers.
