We experimentally demonstrate that graphene can strongly modulate the scattered light from Fano-resonant plasmonic metasurfaces. The Modulation depth of 1000% is achieved at around 7µm as the graphene carrier concentration changes.
Electromagnetically induced transparency and polarization conversion due to interference between two polarization-selective plasmonic resonances coexisting in the same planar metamaterial are studied. The metasurface represents a periodic array of two topologically distinct metamolecules combined on the same substrate: i) monopole antennas connected to wires and supporting a high-Q resonance radiatively...
We introduce electrically connected Fano-resonant metasurfaces consisting of a periodic array of antennas connected to wires. Possibility of the direct interaction among the antennas by the charge transfer allows for robust high quality Fano resonances.
Successful development of epitaxial Ag as a new plasmonic platform has enabled low-threshold, continuous-wave (CW) operation of a SPASER-enabled nanolaser comprised of a subdiffraction plasmonic cavity and a single InGaN@GaN core-shell nanorod gain medium.
