"Plasmonic Beam Coupling and Shaping"

"A new class of plasmonic interfaces is presented which greatly expands the capability of plasmonics for science and technology. I will discuss: polarization controlled tunable directional coupling of surface plasmons (SP); holographic metasurfaces that generate broadband radially polarized beams, holographic vortex detectors and the generation for the first time of straight propagating diffraction less SP beams (cosine-Gauss beams and bottle beams). These findings have potential applications in quantum information processing, chip interconnects and nanoparticle trapping."
