Single-crystalline gold nanodisks on WS mono- and multilayers: Strong coupling at room temperature
Mathias Geisler, Ximin Cui, Jianfang Wang +11
Engineering light-matter interactions up to the strong-coupling regime at room temperature is one of the cornerstones of modern nanophotonics. Achieving this goal will enable new p…
Stimulated plasmon polariton scattering
Christian Wolff, N. Asger Mortensen
The plasmon and phonon polaritons of two-dimensional (2d) and van-der-Waals materials have recently gained substantial interest. Unfortunately, they are notoriously hard to observe…
Ultra-thin titanium nitride films for refractory spectral selectivity
Alexander S. Roberts, Manohar Chirumamilla, Deyong Wang +4
We demonstrate a selectively emitting optical Fabry-Pérot resonator based on a few-nm-thin continuous metallic titanium nitride film, separated by a dielectric spacer from an optic…
On the time evolution at a fluctuating exceptional point
Christian Wolff, Christos Tserkezis, N. Asger Mortensen
We theoretically evaluate the impact of drift-free noise on the dynamics of -symmetric non-Hermitian systems with an exceptional point, which have recently been propo…
Direct characterization of near-field coupling in gap plasmon-based metasurfaces
Rucha Deshpande, Vladimir A. Zenin, Fei Ding +2
Metasurfaces based on gap surface-plasmon resonators allow one to arbitrarily control the phase, amplitude and polarization of reflected light with high efficiency. However, the pe…
Edge-dependent reflection and inherited fine structure of higher-order plasmons in graphene nanoribbons
Kåre Obel Wedel, N. Asger Mortensen, Kristian S. Thygesen +1
We investigate higher-order plasmons in graphene nanoribbons, and present how electronic edge states and wavefunction fine structure influence the graphene plasmons. Based on neare…
