Focusing of in-plane hyperbolic polaritons in van der Waals crystals with tailored infrared nanoantennas
Javier Martín-Sánchez, Jiahua Duan, Javier Taboada-Gutiérrez +9
Phonon polaritons (PhPs),light coupled to lattice vibrations,with in-plane hyperbolic dispersion exhibit ray-like propagation with large wavevectors and enhanced density of optical…
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…
Giant optical anisotropy in transition metal dichalcogenides for next-generation photonics
G. A. Ermolaev, D. V. Grudinin, Y. V. Stebunov +17
Large optical anisotropy observed in a broad spectral range is of paramount importance for efficient light manipulation in countless devices. Although a giant anisotropy was recent…
Analytical approximations for the dispersion of electromagnetic modes in slabs of biaxial crystals
Gonzalo Álvarez-Pérez, Kirill V. Voronin, Valentyn S. Volkov +2
Anisotropic crystals have recently attracted considerable attention because of their ability to support polaritons with a variety of unique properties, such as hyperbolic dispersio…
