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…

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…
