Strong coupling in a Au plasmonic antenna-SiO layer system: a hybrid mode analysis
Pavel Gallina, Michal Kvapil, Jiří Liška +5
A detailed analysis of the optical response of a system accommodating several coupled modes is needed for the complete understanding of the strong coupling effect. In this paper, w…
Low-loss tunable infrared plasmons in the high-mobility perovskite (Ba,La)SnO
Hongbin Yang, Andrea Konečná, Xianghan Xu +4
BaSnO exhibits the highest carrier mobility among perovskite oxides, making it ideal for oxide electronics. Collective charge carrier oscillations, plasmons, are expected to ar…
Probing the electromagnetic response of dielectric antennas by vortex electron beams
Andrea Konecna, Mikolaj K. Schmidt, Rainer Hillenbrand +1
Focused beams of electrons, which act as both sources, and sensors of electric fields, can be used to characterise the electric response of complex photonic systems by locally prob…
Inelastic Scattering of Electron Beams by Nonreciprocal Nanotructures
Renwen Yu, Andrea Konečná, F. Javier García de Abajo
Probing optical excitations with high resolution is important for understanding their dynamics and controlling their interaction with other photonic elements. This can be done usin…
Nonlinear Tunable Vibrational Response in Hexagonal Boron Nitride
Fadil Iyikanat, Andrea Konečná, F. Javier García de Abajo
Nonlinear light-matter interactions in structured materials are the source of exciting properties and enable vanguard applications in photonics. However, the magnitude of nonlinear…
Revealing Nanoscale Confinement Effects on Hyperbolic Phonon Polaritons with an Electron Beam
Andrea Konečná, Jiahan Li, James H. Edgar +2
Hyperbolic phonon polaritons (HPhPs) in hexagonal boron nitride (hBN) enable the direct manipulation of mid-infrared light at nanometer scales, many orders of magnitude below the f…
Atomic-Scale Vibrational Mapping and Isotope Identification with Electron Beams
Andrea Konečná, Fadil Iyikanat, F. Javier García de Abajo
Transmission electron microscopy and spectroscopy currently enable the acquisition of spatially resolved spectral information from a specimen by focusing electron beams down to a s…
