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…
Amplitude- and phase-resolved nano-imaging and nano-spectroscopy of polaritons in liquid environment
Divya Virmani, Andrei Bylinkin, Irene Dolado Lopez +3
Localized and propagating polaritons allow for highly sensitive analysis of (bio)chemical substances and processes. Nanoimaging of the polaritons evanescent fields allows for criti…
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…
Infrared permittivity of the biaxial van der Waals semiconductor -MoO from near- and far-field correlative studies
Gonzalo Álvarez-Pérez, Thomas G. Folland, Ion Errea +13
The biaxial van der Waals semiconductor -phase molybdenum trioxide (-MoO) has recently received significant attention due to its ability to support highly anisotropic pho…
