Abstract

Laser processing technology provides an effective means of controlling the colors of plasmonic metamaterials across large areas with micrometer resolution, allowing for the printing of images with structural colors that are visible to the naked eye. Despite the inhomogeneity in size and spatial distribution of metallic nano-objects inherent to the laser process, the colors generated are highly reproducible and can exhibit unique visual properties due to collective resonances that add to the localized surface plasmon resonances (LSPR). Here we investigate the effect of inhomogeneity in size and position on the surface lattice resonances that strongly contribute to the strong dichroism observed in laser-induced sself-organized metasurfaces. By exploiting the dichroic properties of these structures, we have successfully implemented two- and three-image multiplexing using direct laser printing techniques. These results demonstrate the potential of nanosecond laser processing for high-end anticounterfeiting applications. By combining our experimental findings with advanced computational approaches, we aim to advance the creation of even more complex and sophisticated images with enhanced optical properties.
