Electrically-driven optical antennas
Johannes Kern, René Kullock, Jord C. Prangsma +3
Unlike radiowave antennas, optical nanoantennas so far cannot be fed by electrical generators. Instead, they are driven by light or via optically active materials in their proximit…
Atomic-scale confinement of optical fields
Johannes Kern, Swen Grossmann, Nadezda V. Tarakina +7
In the presence of matter there is no fundamental limit preventing confinement of visible light even down to atomic scales. Achieving such confinement and the corresponding intensi…
Dynamics of four-photon photoluminescence in gold nanoantennas
P. Biagioni, D. Brida, J. -S. Huang +5
Two-pulse correlation is employed to investigate the temporal dynamics of both two-photon photoluminescence (2PPL) and four-photon photoluminescence (4PPL) in resonant and nonreson…
Atomically flat single-crystalline gold nanostructures for plasmonic nanocircuitry
Jer-Shing Huang, Victor Callegari, Peter Geisler +12
Deep subwavelength integration of high-definition plasmonic nanostructures is of key importance for the development of future optical nanocircuitry for high-speed communication, qu…
Mode imaging and selection in strongly coupled nanoantennas
Jer-Shing Huang, Johannes Kern, Peter Geisler +5
The number of eigenmodes in plasmonic nanostructures increases with complexity due to mode hybridization, raising the need for efficient mode characterization and selection. Here w…
