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.

Keywords: coupler; focus ion beam; reflector; self-aligned; surface plasmons.
