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…
Sub-wavelength localization of near-fields in coupled metallic spheres for single emitter polarization analysis
Po-Nan Li, Hsiu-Hao Tsao, Jer-Shing Huang +1
We numerically demonstrate selective near-field localization determined by the polarization state of a single emitter coupled to plasmonic nano-cluster. Seven gold nanospheres are…
Nanoantennas for visible and infrared radiation
Paolo Biagioni, Jer-Shing Huang, Bert Hecht
Nanoantennas for visible and infrared radiation can strongly enhance the interaction of light with nanoscale matter by their ability to efficiently link propagating and spatially l…
