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…
Seeing Beyond RGB Capabilities: Data-Driven and Physics-Guided Broadband Spectral Extrapolation of Plasmonic Nanostructures by Deep Learning
Mohammadrahim Kazemzadeh, Banghuan Zhang, Tao He +13
Localized surface plasmons can confine light within a deep-subwavelength volume comparable to the scale of atoms and molecules, enabling ultrasensitive responses to near-field vari…
Long-range mid-infrared energy transfer mediated by hyperbolic phonon polaritons
Gonzalo Ãlvarez-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…
Spatiotemporal Raman Probing of Molecular Transport in sub-2-nm Plasmonic Quasi-2D Nanochannels
Haoran Liu, Zihe Jiang, Zhiwei Hu +9
Capturing molecular dynamics in nanoconfined channels with high spatiotemporal resolution is a key challenge in nanoscience, crucial for advancing catalysis, energy conversion, and…
Quantitative Benchmarking of Remote Excitation in Plasmonic Sensing with Enhanced Signal-to-Noise Ratio
Tao He, Haoran Liu, Zihe Jiang +10
Remote excitation using guided optical modes -- such as waveguides, fibers, or surface waves -- offers a promising alternative to direct optical excitation for surface-enhanced Ram…
