Abstract
Single and multiple holes in optically thick gold layers are investigated with cathodoluminescence to obtain optical information beyond the diffraction limit. Excitation patterns and spectral shapes are observed to shift when the hole shape is varied. It is shown that the specific relative orientation of dimers and trimers of holes leads to shifts in the spectrum and changes of the excitation patterns.
