Efficient energy propagation through self-assembled gold nanoparticle chain waveguides
Fatih N. Gür, Cillian P. T. McPolin, Søren Raza +9
The strong interaction of light with metallic nanoparticles enables field confinement well below the diffraction limit. Plasmonic waveguides consisting of metal nanoparticle chains…
Stability of Thin Film Refractory Plasmonic Materials Taken to High Temperatures in Air
Matthew P. Wells, Gomathi Gobalakrichenane, Ryan Bower +9
Materials such as W, TiN, and SrRuO3 (SRO) have been suggested as promising alternatives to Au and Ag in plasmonic applications owing to their refractory properties. However, inves…
Janus and Huygens' dipolar sources for near-field directionality
Michela F. Picardi, Anatoly V. Zayats, Francisco J. Rodríguez-Fortuño
Controlling directionality of emission, scattering and waveguiding is an important requirement in quantum optical technology, integrated photonics and new metasurface designs, as w…
Repulsion of polarized particles from two-dimensional materials
Francisco J. Rodríguez-Fortuño, Michela F. Picardi, Anatoly V. Zayats
Repulsion of nanoparticles, molecules and atoms from surfaces can have important applications in nanomechanical devices, microfluidics, optical manipulation and atom optics. Here,…
Titanium oxynitride thin films with tunable double epsilon-near-zero behaviour
Laurentiu Braic, Nikolaos Vasilantonakis, Andrei P. Mihai +10
Titanium Oxynitride (TiOxNy) thin films are fabricated using reactive magnetron sputtering. The mechanism of their growth formation is explained and their optical properties are pr…
