Misalignment between the Directions of Propagation and Decay of Nanoscale-confined Polaritons
Kirill V. Voronin, Gonzalo Ãlvarez-Pérez, Aitana Tarazaga MartÃn-Luengo +2
Anisotropic van der Waals crystals have gained significant attention in nanooptics and optoelectronics due to their unconventional optical properties, including anomalous reflectio…
Roadmap for Photonics with 2D Materials
F. Javier GarcÃa de Abajo, D. N. Basov, Frank H. L. Koppens +145
Triggered by the development of exfoliation and the identification of a wide range of extraordinary physical properties in self-standing films consisting of one or few atomic layer…
Ultraconfined THz Phonon Polaritons in Hafnium Dichalcogenides
R. A. Kowalski, N. S. Mueller, G. Ãlvarez-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 DÃaz-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 Ãlvarez-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. Ãlvarez-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…
