End-fire coupling efficiencies of surface plasmons for silver, gold, and plasmonic nitride compounds
We present a semi-analytical study exploring the end-fire coupling of a free-space incident beam into a surface plasmon propagating along the interface of a dielectric and a lossy plasmonic material. Using a projection method that calculates the surface plasmon coupling efficiencies for this configuration, we explain in detail how the challenges of including loss, and thus having complex permittivities, have been overcome. A comparison is made of the coupling efficiencies of four plasmonic...[Show more]
