Free electrons unveil nanolaser physics at the sub-picosecond and nanometer scale
Cléo Santini, Thi Huong Ngo, Luiz H. G. Tizei +14
Semiconducting nanowire lasers (NWLs) constitute nanoscale modular and tunable light sources, essential components for integrated optoelectronics. However, advancing NWL operation…
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…
Spontaneous and Stimulated Electron-Photon Interactions in Nanoscale Plasmonic Near Fields
Matthias Liebtrau, Murat Sivis, Armin Feist +6
We demonstrate spatially-resolved measurements of spontaneous and stimulated electron-photon interactions in nanoscale optical near fields using electron energy-loss spectroscopy (…
Optical polarization analogue in free electrons beams
Hugo Lourenço-Martins, Davy Gérard, Mathieu Kociak
Fast electrons spectromicroscopies enable to measure quantitatively the optical response of excitations with unrivaled spatial resolution. However, due to their inherently scalar n…
Probing chirality with inelastic electron-light scattering
Tyler R. Harvey, Jan-Wilke Henke, Ofer Kfir +4
Circular dichroism spectroscopy is an essential technique for understanding molecular structure and magnetic materials, but spatial resolution is limited by the wavelength of light…
Controlling free electrons with optical whispering-gallery modes
Ofer Kfir, Hugo Lourenço-Martins, Gero Storeck +5
Free-electron beams serve as uniquely versatile probes of microscopic structure and composition, and have repeatedly revolutionized atomic-scale imaging, from solid-state physics t…
Visualizing plasmon-exciton polaritons at the nanoscale using electron microscopy
Andrew B. Yankovich, Battulga Munkhbat, Denis G. Baranov +7
Polaritons are compositional light-matter quasiparticles that have recently enabled remarkable breakthroughs in quantum and nonlinear optics, as well as in material science. Despit…
Self-hybridization within non-Hermitian plasmonic systems
H. Lourenço-Martins, P. Das, L. H. G. Tizei +2
Common intuition in physics is based on the concept of orthogonal eigenmodes. Those are well de- fined solutions of Hermitian equations used to describe many physical situations, f…
Probing the symmetry of the potential of localized surface plasmon resonances with phase-shaped electron beams
Giulio Guzzinati, Armand Béché, Hugo Lourenço--Martins +3
Plasmonics, the science and technology of the interaction of light with metallic objects, is fundamentally changing the way we can detect, generate and manipulate light. Although t…
