Laser-induced fabrication of metasurfaces
An array of periodically arranged nanostructures in a metallic film with plasmonic properties generates hybrid plasmonic modes due to the interaction of localized surface plasmon and surface plasmon propagating at the metal-dielectric interface. Since structures generating hybrid plasmonic modes have higher optical sensitivity, they can be used in a wide range of applications. The laser-based approach allows for a significant reduction in the cost of producing hybrid plasmonic structures, as it is a one-step technology that does not use expensive vacuum support equipment and is capable of forming structures over a large area (down to 1 cm2). This makes the derivatives produced in this way particularly attractive for commercial applications. In this work, nanostructures will be formed in thin metallic coatings by placing them in different media in order to investigate the differences in the morphology of the formed nanostructures and the influence on the optical response of such formations, and to study their photoluminescence properties.
