Plasmonic resonance effects for tandem receiving-transmitting nanoantennas.
A nanoplasmonic "transceiver" was assembled to examine the efficiency of coupled plasmonic antennas and their resonance interactions. In particular, plasmonic focusing receiver antenna coupled to transmitting annular antenna having a short central plasmonic wire was measured. The receiver collected incoming radially polarized light and efficiently focused and coupled it to a rear side transmitter comprised of a short resonant plasmonic wire and annular aperture. Transmission spectra exhibited a substantial signature of the wire Fabry-Perot resonances. The wire antenna crossection was improved by nearly 3 orders of magnitude by the focusing antenna system.
