Generalized nonlocal optical response in nanoplasmonics
N. Asger Mortensen, Søren Raza, Martijn Wubs +2
Metallic nanostructures exhibit a multitude of optical resonances associated with localized surface plasmon excitations. Recent observations of plasmonic phenomena at the sub-nanom…
Plasmon-phonon coupling in large-area graphene dot and antidot arrays
Xiaolong Zhu, Weihua Wang, Wei Yan +6
Nanostructured graphene on SiO2 substrates pave the way for enhanced light-matter interactions and explorations of strong plasmon-phonon hybridization in the mid-infrared regime. U…
Absorption and eigenmode calculation for one-dimensional periodic metallic structures using the hydrodynamic approximation
Avner Yanai, N. Asger Mortensen, Uriel Levy
We develop a modal method that solves Maxwell's equations in the presence of the linearized hydrodynamic correction. Using this approach, it is now possible to calculate the full d…
Broadening of plasmonic resonance due to electron collisions with nanoparticle boundary: quantum-mechanical consideration
Alexander V. Uskov, Igor E. Protsenko, N. Asger Mortensen +1
We present a quantum mechanical approach to calculate broadening of plasmonic resonances in metallic nanostructures due to collisions of electrons with the surface of the structure…
Enhanced light-matter interaction in graphene-covered gold nanovoid arrays
Xiaolong Zhu, Lei Shi, Michael S. Schmidt +5
The combination of graphene with noble-metal nanostructures is currently being explored for strong light-graphene interaction enhanced by plasmons. We introduce a novel hybrid grap…
Nonlocal response in thin-film waveguides: loss versus nonlocality and breaking of complementarity
Søren Raza, Thomas Christensen, Martijn Wubs +2
We investigate the effects of nonlocal response on the surface-plasmon polariton guiding properties of the metal-insulator (MI), metal-insulator-metal (MIM), and insulator-metal-in…
Hybridization of quantum plasmon modes in coupled nanowires: From the classical to the tunneling regime
Kirsten Andersen, Kristian L. Jensen, N. Asger Mortensen +1
We present full quantum mechanical calculations of the hybridized plasmon modes of two nanowires at small separation, providing real space visualization of the modes in the transit…
Hyperbolic metamaterial lens with hydrodynamic nonlocal response
Wei Yan, N. Asger Mortensen, Martijn Wubs
We investigate the effects of hydrodynamic nonlocal response in hyperbolic metamaterials (HMMs), focusing on the experimentally realizable parameter regime where unit cells are muc…
Experimental observation of plasmons in a graphene monolayer resting on a two-dimensional subwavelength silicon grating
Xiaolong Zhu, Wei Yan, Peter Uhd Jepsen +3
We experimentally demonstrate graphene-plasmon polariton excitation in a continuous graphene monolayer resting on a two-dimensional subwavelength silicon grating. The subwavelength…
