Near-Field Interference for the Unidirectional Excitation of Electromagnetic Guided Modes

Francisco J. Rodríguez-Fortuño

Daniel O’cOnnor

Controlling Light Propagation: Surface plasmons are light-induced collective electronic excitations in a metal that offer the possibility of manufacturing optoelectronic devices at nanometer scale. Before such shrinking can be achieved, the propagation direction and lifetime of the plasmonic excitations have to be controlled (see the Perspective by Miroshnichenko and Kivshar ). Rodríguez-Fortuño et al. (p. 328 ) show how this is done using polarized light. Alternatively, using an array of metallic nanoantennae (in this case, slits) patterned into a thin gold film, Lin et al. (p. 331 ) present a further improvement on current plasmonic coupling schemes that has the potential to encode information contained in both the intensity and polarization of light.

Spin–orbit coupling in surface plasmon scattering by nanostructures

The spin Hall effect leads to the separation of electrons with opposite spins in different directions perpendicular to the electric current flow because of interaction between spin and orbital angular momenta. Similarly, photons with opposite spins (different handedness of circular light polarization) may take different trajectories when interacting with metasurfaces that break spatial inversion symmetry or when the inversion symmetry is broken by the radiation of a dipole near an interface. Here we demonstrate a reciprocal effect of spin–orbit coupling when the direction of propagation of a surface plasmon wave, which intrinsically has unusual transverse spin, determines a scattering direction of spin-carrying photons. This spin–orbit coupling effect is an optical analogue of the spin injection in solid-state spintronic devices (inverse spin Hall effect) and may be important for optical information processing, quantum optical technology and topological surface metrology.

Gap plasmon polariton structure for very efficient microscale-to-nanoscale interfacing

P. Ginzburg

David Arbel

Meir Orenstein

The seamless transition between microscale photonics and nanoscale plasmonics requires overpassing different waveguiding mechanisms and a few orders of magnitude in the lateral dimension. Exploiting gap plasmon–polariton waves both at the microscale and nanoscale with an ultrashort (few micrometers) non adiabatic tapered gap plasmon waveguide, we show theoretically that very high-power transfer efficiency

(\sim 70 %)

is achieved. The same mechanism may be used to harvest impinging light waves and direct them into a nanhole or slit to exhibit an anomalous transmission without the conventional periodic structures. The interplay of plasmonic and oscillating modes is analyzed.

Microscopic model of Purcell enhancement in hyperbolic metamaterials

Alexander N. Poddubny

Pavel A. Belov

P. Ginzburg

Anatoly V. Zayats

Yuri S. Kivshar

We study theoretically the dramatic enhancement of spontaneous emission in metamaterials with the hyperbolic dispersion modeled as a cubic lattice of anisotropic resonant dipoles. We analyze the dependence of the Purcell factor on the source position in the lattice unit cell and demonstrate that the optimal emitter positions needed to achieve large Purcell factors and Lamb shifts are in the local field maxima. We show that the calculated Green function has a characteristic crosslike shape, spatially modulated due to the structural discreteness. Our basic microscopic theory provides fundamental insights into the rapidly developing field of hyperbolic metamaterials.
