High topological charge lasing in quasicrystals
Kristian Arjas, Jani M. Taskinen, Rebecca Heilmann +2
Photonic modes exhibiting a polarization winding akin to a vortex possess an integer topological charge. Lasing with topological charge 1 or 2 can be realized in periodic lattices…
All-optical switching at the two-photon limit with interference-localized states
Ville A. J. Pyykkönen, Grazia Salerno, Jaakko Kähärä +1
We propose a single-photon-by-single-photon all-optical switch concept based on interference-localized states on lattices and their delocalization by interaction. In its 'open' ope…
Loss-driven topological transitions in lasing
Grazia Salerno, Rebecca Heilmann, Kristian Arjas +3
We experimentally observe lasing in a hexamer plasmonic lattice and find that when tuning the scale of the unit cell, the polarization winding of the emission changes. By a theoret…
