This bachelor’s thesis deals with optical color filters composed of plasmonically active nanostructures and studies the parameters which influence the performance of such filters. Using electron beam litography and selective reactive ion etching, plasmonic hole-like filters were prepared in alumina film on fused silica substrate. The fabricated arrays of nanostructures, acting as optical filters, varied in shape and size of the nanostructures, distances among the nanostructures and their lateral arrangement within the arrays. The influence of these factors on transmission spectra of plasmonic filters was experimentally analysed using optical spectroscopy. A majority of the observed alternations of the measured transmission spectra was consistent with the research study which is, as well, part of this thesis. The highest color filtering selectivity was observed in arrays with divided square structure shape which also exhibited decent transmittance.
