Misalignment between the Directions of Propagation and Decay of Nanoscale-confined Polaritons
Kirill V. Voronin, Gonzalo Álvarez-Pérez, Aitana Tarazaga Martín-Luengo +2
Anisotropic van der Waals crystals have gained significant attention in nanooptics and optoelectronics due to their unconventional optical properties, including anomalous reflectio…
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…
Visualization of topological shear polaritons in gypsum thin films
Pablo Díaz-Núñez, Christian Lanza, Ziwei Wang +10
Low symmetry crystals have recently emerged as a platform for exploring novel light-matter interactions in the form of hyperbolic shear polaritons. These excitations exhibit unique…
Broad Spectral Tuning of Ultra-Low Loss Polaritons in a van der Waals Crystal by Intercalation
Javier Taboada-Gutiérrez, Gonzalo Álvarez-Pérez, Jiahua Duan +17
Phonon polaritons (PhPs) -- light coupled to lattice vibrations -- in polar van der Waals (vdW) crystals are promising candidates for controlling the flow of energy at the nanoscal…
Unidirectional Ray Polaritons in Twisted Asymmetric Stacks
J. Álvarez-Cuervo, M. Obst, S. Dixit +25
The vast repository of van der Waals (vdW) materials supporting polaritons offers numerous possibilities to tailor electromagnetic waves at the nanoscale. The development of twisto…
Extreme light confinement and control in low-symmetry phonon-polaritonic crystals
Emanuele Galiffi, Giulia Carini, Xiang Ni +9
Polaritons are a hybrid class of quasiparticles originating from the strong and resonant coupling between light and matter excitations. Recent years have witnessed a surge of inter…
