title: Single nanoparticle couplers for plasmonic waveguides.
abstract: A single nanoparticle antenna, can be used as an efficient coupler for plasmonic nanowire waveguides. The coup-ling of light into the surface plasmon polaritons on a nanowire can be suppressed or enhanced depending on the surface plasmon resonances of the nanoantenna. The coupler is compacted and can be simply controlled using focus ion beam.
