A fully nanoscopic dielectric laser
Günter Kewes, Rogelio Rodriguez-Oliveros, Kathrin Höfner +3
In this article, we introduce the concept of a dielectric nanolaser that is nanoscopic in all spatial dimensions. Our proposal is based on dielectric nanoparticles of high refracti…
Limitations of Particle-Based Spasers
Günter Kewes, Kathrin Herrmann, Rogelio Rodríguez-Oliveros +3
We present a semi-classical analytic model for spherical core-shell surface plasmon lasers. Within this model, we drop the widely used one-mode approximations in favor of fully ele…
Evidence for graphene plasmons in the visible spectral range probed by molecules
Philipp Lange, Günter Kewes, Nikolai Severin +2
Graphene is considered to be plasmon active only up to the infrared based on combined tight binding model and random phase approximation calculations. Here we show that the optical…
