Active control of phase matching in nonlinear metasurfaces using Pancharatnam--Berry phase
Madona Mekhael, Roman Calpe, Tommi K. Hakala +2
Reconfiguring the spectral output of nonlinear metasurfaces after fabrication remains challenging. We address this by exploiting the nonlinear Pancharatnam--Berry phase of …

Scattering Dominated Spatial Coherence and Phase Correlation Properties in Plasmonic Lattice Lasers
Janne I. Heikkinen, Benjamin Asamoah, Roman Calpe +3
We present a comprehensive study of the polarization and spatial coherence properties of the lasing modes supported by a 4-fold symmetric plasmonic lattice. By modifying only, the…
