Abstract

A novel optical coupler to access free-space optical signals in subwavelength scale into dielectric waveguide via a plasmonic concentrator and a dielectric microring with field enhancement is proposed. The coupler is useful as it combines the plasmonic concentrator, which is used to access optical signals in subwavelength scale, a microring resonator for the coupling, with the dielectric waveguide for long distance optical transmission and processing.
