چکیده
In this work, we demonstrate a new directional coupling scheme for efficient light coupling between photonic Si3N4 and plasmonic Au-based metallic slot waveguides. The plasmonic-photonic hybrid waveguide structure is capable of supporting guided modes with even and odd symmetry. This feature can lead to the development of an efficient power exchange mechanism which can achieve power transmission per transition over 68% and coupling lengths of the order of just several microns. Keywords— Plasmonics, hybrid slot waveguides, directional coupling, coupling efficiency.
