Probing Graphene's Nonlocality with Singular Metasurfaces
E. Galiffi, P. A. Huidobro, P. A. D. Gonçalves +2
Singular graphene metasurfaces, conductivity gratings realized by periodically suppressing the local doping level of a graphene sheet, have recently been proposed to efficiently ha…
On the applicability of quantum-optical concepts in strong-coupling nanophotonics
C. Tserkezis, A. I. Fernández-Domínguez, P. A. D. Gonçalves +7
Rooted in quantum optics and benefiting from its well-established foundations, strong coupling in nanophotonics has experienced increasing popularity in recent years. With nanophot…
Plasmon-Emitter Interactions at the Nanoscale
P. A. D. Gonçalves, Thomas Christensen, Nicholas Rivera +3
Plasmon-emitter interactions are of paramount importance in modern nanoplasmonics and are generally maximal at short emitter-surface separations. However, when the separation falls…
Direct generation of tunable orbital angular momentum beams in microring lasers with broadband exceptional points
William E. Hayenga, Jinhan Ren, Midya Parto +7
Non-Hermitian exceptional points (EPs) represent a special type of degeneracy where not only the eigenvalues coalesce, but also the eigenstates tend to collapse on each other. Rece…
Unidirectional single-photon emission from germanium-vacancy zero-phonon lines: Deterministic emitter-waveguide interfacing at plasmonic hot spots
Hamidreza Siampour, Ou Wang, Vladimir A. Zenin +10
Striving for nanometer-sized solid-state single-photon sources, we investigate atom-like quantum emitters based on single germanium vacancy (GeV) centers isolated in crystalline na…
Enhanced ponderomotive force in graphene due to interband resonance
Christian Wolff, Christos Tserkezis, N. Asger Mortensen
We analyze intrinsic nonlinearities in two-dimensional polaritonic materials interacting with an optical wave. Focusing on the case of graphene, we show that the second-order nonli…
