Imaging and controlling plasmonic interference fields at buried interfaces

Fabrizio Carbone, Brett Eugene Barwick, Tom Theodorus Antonius Lummen, Gabriele Berruto

Capturing and controlling plasmons at buried interfaces with nanometre and femtosecond resolution has yet to be achieved and is critical for next generation plasmonic devices. Here we use light to excite plasmonic interference patterns at a buried metal-di ...

SPR Sensor with Ultranarrow Magnetoplasmonic Resonance

Serguei Sekatski, Pavel Kapralov

We present the results of experimental investigations of the ultralong-range propagating magnetoplasmons in the specially designed heterostructure. The propagation distance of the surface plasmon increases up to 35 pm due to the inclusion of the photonic c ...

Negative plasmon dispersion in 2H-NbS2 beyond the charge-density-wave interpretation

Helmuth Berger

We examine the experimental and theoretical electron-energy loss spectra in 2H-Cu0.2NbS2 and find that the 1 eV plasmon in this material does not exhibit the regular positive quadratic plasmon dispersion that would be expected for a normal broad-parabolic- ...

Controlling the nonlinear optical properties of plasmonic nanoparticles with the phase of their linear response

Olivier Martin, Gabriel David Bernasconi, Jérémy Butet, Kuang-Yu Yang

We numerically investigate the second harmonic generation from different plasmonic systems and evidence the key role played in their nonlinear response by the phase at the fundamental wavelength. In the case of a single plasmonic nanorod, the interference ...
