Abstract : Optical near-field plates were designed using antisymmetric plasmon modes to generate abrupt phase changes within a fraction of a wavelength. Plasmonic filters were developed and transmission color filtering was accomplished. The polarization property and the pitch-dependent color filtering was combined in a specially designed structure, where the polarization of light can be easily visualized. Light funneling in metallic nanostructures was studied theoretically and experimentally. We introduced a model of an aperture coupled to an oscillator that gives perfect transmission in the absence of losses. The funneling capacity of a nano-groove is slightly smaller than one wavelength.
