Optical skyrmions in evanescent electromagnetic fields
S. Tsesses, E. Ostrovsky, K. Cohen +3
Topological defects play a key role in a variety of physical systems, ranging from high-energy to solid state physics. They yield fascinating emergent phenomena and serve as a brid…
Nanoscale Control over Optical Dislocations
Evgeny Ostrovsky, Kobi Cohen, Bergin Gjonaj +1
High-order optical vortices are inherently unstable, as they tend to split up under perturbation to a series of vortices with unity charge. Control over the perturbation opens up a…
Linearly Dichroic Plasmonic Lens and Hetero-Chiral Structures
Grisha Spektor, Asaf David, Bergin Gjonaj +2
We present theoretical and experimental study of plasmonic Hetero-Chiral structures, comprised of constituents with opposite chirality. We devise, simulate and experimentally demon…
Controlling plasmonic Bloch modes on periodic nanostructures
B. Gjonaj, J. Aulbach, P. M. Johnson +3
We study and actively control the coherent properties of Surface Plasmon Polaritons (SPPs) optically exited on a nano-hole array. Amplitude and phase of the optical excitation are…
Control of light transmission through opaque scattering media in space and time
Jochen Aulbach, Bergin Gjonaj, Patrick M. Johnson +2
We report the first experimental demonstration of combined spatial and temporal control of light trajectories through opaque media. This control is achieved by solely manipulating…
Digital Plasmonics
Bergin Gjonaj, Jochen Aulbach, Patrick M. Johnson +3
The field of plasmonics offers a route to control light fields with metallic nanostructures through the excitation of Surface Plasmon Polaritons (SPPs). These surface waves, bound…
