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…
Color Routing and Beam Steering of Single-Molecule Emission with a Spherical Silicon Nanoantenna
Maria Sanz-Paz, Nicole Siegel, Guillermo Serrera +7
Single-photon emitters radiate as electric dipoles, which limits light collection efficiency and complicates integration into flat photonic devices. Developing nanophotonic structu…
Polymer-Shell Coating of Mie-Resonant Silicon Nanospheres for Controlled Fabrication of Self-Assembled Monolayer
Oanh Vu, Jialu Song, Hiroshi Sugimoto +1
A polymer shell offers a unique opportunity to tailor structural and optical properties of optically functional nanoparticles and their ensembles. Here, we develop a process to coa…
Distance dependent interaction between a single emitter and a single dielectric nanoparticle using DNA origami
Nicole Siegel, MarÃa Sanz-Paz, Javier González-Colsa +8
Optical nanoantennas can manipulate light-matter interactions at the nanoscale, modifying the emission properties of nearby single photon emitters. To date, most optical antennas a…
Routing Light Emission from Monolayer MoS by Mie Resonances of Crystalline Silicon Nanospheres
Keisuke Ozawa, Hiroshi Sugimoto, Daisuke Shima +8
A dielectric Mie-resonant nanoantenna is capable of controlling the directionality of the emission from nearby quantum emitters through the excitation of multiple degenerate Mie re…
