Revealing time characteristics of optical excitations in dielectric and plasmonic structures through cathodoluminescence interferometry

Evelijn Akerboom, Hirohsi Sugimoto, Minoru Fujii +5

Cathodoluminescence (CL) spectroscopy provides access to optical excitations with nanometer spatial resolution, but direct time-resolved measurements of optical resonances remain c…

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…
