Twistoptics in Planar Heterostructures with an Arbitrary Number of Rotated 3D Thin Layers and 2D Conductive Sheets
Christian Lanza, José Álvarez-Cuervo, Kirill V. Voronin +5
Twistoptics has recently emerged as a branch of nano-optics that explores light propagation in stacks of thin anisotropic layers rotated relative to one another. The concept is par…
Fast Programming of In-Plane Hyperbolic Phonon Polariton Optics Through van der Waals Crystals using the Phase-Change Material In3SbTe2
Lina Jäckering, Umberto Saldarelli, Aaron Moos +8
The high directionality of hyperbolic phonon polaritons (HPhPs) has opened radically new ways to route and steer the flow of energy at the nanoscale. However, launching HPhPs requi…
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…
Tailoring phonon-driven responses in α-MoO3 through isotopic enrichment
Thiago S. Arnaud, Ryan W. Spangler, Johnathan D. Georgaras +29
The implementation of polaritonic materials into nanoscale devices requires selective tuning of parameters to realize desired spectral or thermal responses. One robust material is…
Directional strong coupling at the nanoscale between hyperbolic polaritons and organic molecules
Ana I. F. Tresguerres-Mata, Olga G. Matveeva, Christian Lanza +17
Strong coupling (SC) is a fundamental concept in physics that describes extreme interactions between light and matter. Recent experiments have demonstrated SC at the nanometer scal…
Ultraconfined THz Phonon Polaritons in Hafnium Dichalcogenides
R. A. Kowalski, N. S. Mueller, G. Álvarez-Pérez +18
The confinement of electromagnetic radiation to subwavelength scales relies on strong light-matter interactions. In the infrared (IR) and terahertz (THz) spectral ranges, phonon po…
Canalization-based super-resolution imaging using a single van der Waals layer
Jiahua Duan, Aitana Tarazaga Martin-Luengo, Christian Lanza +7
Canalization is an optical phenomenon that enables unidirectional propagation of light in a natural way, i.e., without the need for predefined waveguiding designs. Predicted years…
Planar nano-optics in anisotropic media: anomalous refraction and diffraction-free lensing of highly confined polaritons
J. Duan, G. Álvarez-Pérez, A. I. F. Tresguerres-Mata +13
As one of the most fundamental optical phenomena, refraction between isotropic media is characterized by light bending towards the normal to the boundary when passing from a low- t…
Enabling propagation of anisotropic polaritons along forbidden directions via a topological transition
Jiahua Duan, Gonzalo Álvarez-Pérez, Kirill V. Voronin +6
Recent discoveries of polaritons in van der Waals (vdW) crystals with directional in-plane propagation, ultra-low losses, and broad spectral tunability have opened the door for unp…
Goodness-of-fit tests for functional linear models based on integrated projections
Eduardo García-Portugués, Javier Álvarez-Liébana, Gonzalo Álvarez-Pérez +1
Functional linear models are one of the most fundamental tools to assess the relation between two random variables of a functional or scalar nature. This contribution proposes a go…
Nanoscale-confined Terahertz Polaritons in a van der Waals Crystal
Thales V. A. G. de Oliveira, Tobias Nörenberg, Gonzalo Álvarez-Pérez +11
Electromagnetic field confinement is crucial for nanophotonic technologies, since it allows for enhancing light-matter interactions, thus enabling light manipulation in deep sub-wa…
