Active and Passive Tuning of Ultranarrow Resonances in Polaritonic Nanoantennas
(Wiley, 2022-03-10)
[EN] Optical nanoantennas are of great importance for photonic devices and spectroscopy due to their capability of squeezing light at the nanoscale and enhancing light-matter interactions. Among them, nanoantennas made of ...
Planar refraction and lensing of highly confined polaritons in anisotropic media
(Nature, 2021-07-15)
Refraction between isotropic media is characterized by light bending towards the normal to the boundary when passing from a low- to a high-refractive-index medium. However, refraction between anisotropic media is a more ...
