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…
Long-range mid-infrared energy transfer mediated by hyperbolic phonon polaritons
Gonzalo Álvarez-Pérez, Simone De Liberato, Huatian Hu
We provide a framework to theoretically describe long-range energy transfer in single and twisted two-dimensional hyperbolic slabs. We demonstrate that phonon polaritons (PhPs, qua…
Extreme polaritonic interactions in a room-temperature deterministic sub-nanocavity quantum electrodynamic platform
Huatian Hu, Xin Shu, Zhiwei Hu +6
Pushing nanoscale optical confinement to its ultimate limits defines the regime of nano-cavity quantum electrodynamics (nano-cQED), where light--matter interactions approach the fu…
