Spectral Anisotropy in Transition Radiation from Biaxial Media
Sven Ebel, Bibi Mary Francis, Min Seok Jang +4
In anisotropic optical media, the electromagnetic response depends on the orientation of the optical field relative to the material's principal dielectric axes. While this directio…
Beam Routing through Excitons in Transition Metal Dichalcogenide Monolayers
Yonas Lebsir, Jacob Terndrup Heiden, Jorge Barcia Rodríguez +6
Routing light at the nanoscale typically relies on nanostructured surfaces to imprint directionality on the emission. Using low-temperature, angle-resolved cathodoluminescence spec…
Probe- and Substrate-Dependent Visibility of Mie Resonances in Silicon Nanospheres
Yonas Lebsir, Huatian Hu, P. A. D. Gonçalves +5
Silicon nanospheres are high-quality optical resonators and promising building blocks for Mie-tronic devices. While the Mie resonances of an isolated sphere are well understood, pr…
Substrate-Assisted Cathodoluminescence
Sven Ebel, N. Asger Mortensen, Sergii Morozov
Electron-beam-induced luminescence typically relies on direct excitation by high energy primary electrons. Here, we explore properties of an alternative excitation approach where c…
An atlas of photonic and plasmonic materials for cathodoluminescence microscopy
Sven Ebel, Yonas Lebsir, Torgom Yezekyan +2
Cathodoluminescence (CL) microscopy has emerged as a powerful tool for investigating the optical properties of materials at the nanoscale, offering unique insights into the behavio…
Near-field refractometry of van der Waals crystals
Martin Nørgaard, Torgom Yezekyan, Stefan Rolfs +3
Common techniques for measuring refractive indices, such as ellipsometry and goniometry, are ineffective for van der Waals crystal flakes because of their high anisotropy and small…
