Selective probing of longitudinal and transverse plasmon modes with electron phase-matching
Franck Aguilar, Hugo Lourenço-Martins, Damián Montero +3
The optical properties of metallic nanoparticles are dominated by localized surface plasmons (LSPs). Their properties only depend on the constituting material, the size and shape o…
High efficiency coupling of free electrons to sub- modal volume, high-Q photonic cavities
Malo Bézard, Imène Si Hadj Mohand, Luigi Ruggierio +6
We report on the design, realization and experimental investigation by spatially resolved monochromated electron energy loss spectroscopy (EELS) of high quality factor cavities wit…
Tomographic reconstruction of quasistatic surface polariton fields
Raphael Hauer, Georg Haberfehlner, Gerald Kothleitner +2
We theoretically investigate the tomographic reconstruction of the three-dimensional photonic environment of nanoparticles. As input for our reconstruction we use electron energy l…
Local Optical Chirality Induced by Near-Field Mode Interference in Achiral Plasmonic Metamolecules
Andreas Horrer, Yinping Zhang, Davy Gérard +4
When circularly polarized light interacts with a nanostructure, the optical response depends on the geometry of the structure. If the nanostructure is chiral (i.e., it cannot be su…
Unveiling the coupling of single metallic nanoparticles to whispering-gallery microcavities
Yves Auad, Cyrille Hamon, Marcel Tencé +6
Whispering-gallery mode resonators host multiple trapped narrowband circulating optical resonances that find applications in quantum electrodynamics, optomechanics, and sensing. Ho…
Aluminum Cayley trees as scalable, broadband, multi-resonant optical antennas
Thomas Simon, Xiaoyan Li, Jérôme Martin +4
An optical antenna can convert a propagative optical radiation into a localized excitation, and reciprocally. Although optical antennas can be readily created using resonant nanopa…
