Abstract
On-chip manipulation and concentration of propagating surface plasmons is of interest for ultracompact integrated optical circuits. Recently many plasmonic energy-storage devices based on patterned graphene have been proposed, but these nanostructures introduce large edge-electron-scattering losses. This study uses plasmonic Tamm states to enhance and trap propagating plasmons in graphene terminals, where just two unit cells of graphene are enough to squeeze the electromagnetic field into an extremely small mode volume, with remarkably intensity enhancement. This approach should facilitate deep-subwavelength integrated graphene-based trappers, resonators, and biosensors.
