Abstract

We report on the discovery of a new type of optical plasmonic media: by observing absorption lines in a superconducting metamaterial out of Niobium (Nb), we find that the Nb metamaterial shows plasmonic properties at visible wavelengths. This suggests that superconductors are a feasible platform for new generation of plasmonic metadevices.
