Topological lasers generating and multiplexing topological light
B. Bahari, L. -Y. Hsu, S. H. Pan +5
Vortices are topologically stable singularities at the center of a swirl of energy. Optical vortices are conventionally formed using diffractive optics or by bespoke optical elemen…
Designing a broadband and linear polarization metasurface carpet cloak in the visible
L. Y. Hsu, A. Ndao, B. Kanté
In the past few years, carpet cloaking attracted interests because of its feasibility at optical frequencies and potential in stealth technologies. Metasurfaces have been proposed…
Observation of plasmonic exceptional points
J. -H. Park, A. Ndao, W. Cai +5
Non-Hermitian singularities known as exceptional-points (EPs) have been shown to exhibit increased sensitivities but the observation of EPs has so far been limited to wavelength sc…
Extremely Thin Dielectric Metasurface for Carpet Cloaking
LiYi Hsu, Thomas Lepetit, Boubacar Kanté
We demonstrate a novel and simple approach to cloaking a scatterer on a ground plane. We use an extremely thin dielectric metasurface (λ/12) to reshape the wavefronts distorted by…
