Polarization- and wave-vector selective optical metasurface with near-field coupling
Helene Wetter, Jan Wingenbach, Falk Rehberg +3
Metasurfaces are a powerful tool for manipulating light using small structures on the nanoscale. In most meta-surfaces, near-field couplings are treated as unfavorable perturbation…
Exceptional rings in nonlinear non-Hermitian planar optical microcavities: implementation, signal enhancement, and topology
Jan Wingenbach, Laura Ares, Xuekai Ma +4
Non-Hermitian systems hosting exceptional points (EPs) exhibit signal enhancement and unconventional mode dynamics. Going beyond isolated EPs, here we report on the existence of ex…
Universal Topology of Exceptional Points in Nonlinear Non-Hermitian Systems
N. H. Kwong, Jan Wingenbach, Laura Ares +4
Exceptional points (EPs) are non-Hermitian degeneracies where eigenvalues and eigenvectors coalesce, giving rise to unusual physical effects across scientific disciplines. The conc…
