On-chip optoelectronic and all-optical information processing paradigmsrequire compact implementation of signal transfer for which nanoscale surfaceplasmons circuitry offers relevant solutions. This work demonstrates thedirectional signal transmittance mediated by 2D plasmonic eigenmodes supportedby crystalline cavities. Channel devices comprising two mesoscopic triangularinput and output ports and sustaining delocalized, higher-order plasmonresonances in the visible to infra-red range are shown to enable thecontrollable transmittance between two confined entry and exit ports coupledover a distance exceeding 2 $\mu$m. The transmittance is attenuated by > 20dBupon rotating the incident linear polarization, thus offering a convenientswitching mechanism. The optimal transmittance for a given operating wavelengthdepends on the geometrical design of the device that sets the spatial andspectral characteristic of the supporting delocalized mode. Our approach ishighly versatile and opens the way to more complex information processing usingpure plasmonic or hybrid nanophotonic architectures.
