Negative reflection of polaritons at the nanoscale in a low-loss natural medium
Gonzalo Alvarez-Perez, Jiahua Duan, Javier Taboada-Gutierrez +10
Negative reflection occurs when light is reflected towards the same side of the normal to the boundary from which it is incident. This exotic optical phenomenon, which provides a n…
Enhanced Light-Matter Interaction in B-10 Monoisotopic Boron Nitride Infrared Nanoresonators
M. Autore, I. Dolado, P. Li +10
Phonon-polaritons, mixed excitations of light coupled to lattice vibrations (phonons), are emerging as a powerful platform for nanophotonic applications. This is because of their a…
Revealing Nanoscale Confinement Effects on Hyperbolic Phonon Polaritons with an Electron Beam
Andrea Konečná, Jiahan Li, James H. Edgar +2
Hyperbolic phonon polaritons (HPhPs) in hexagonal boron nitride (hBN) enable the direct manipulation of mid-infrared light at nanometer scales, many orders of magnitude below the f…
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…
Unraveling Ultrafast Photoionization in Hexagonal Boron Nitride
Lianjie Xue, Song Liu, Yang Hang +17
The non-linear response of dielectrics to intense, ultrashort electric fields has been a sustained topic of interest for decades with one of its most important applications being f…
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…
