Topological robustness of optical skyrmions through a real-world free-space link
Cade Peters, Vagharshak Hakobyan, Alice Drozdov +3
Structured light offers a promising solution for the increasing data demands of modern optical networks, opening up new degrees of freedom that can be leveraged for greater channel…

Dual-wavelength quantum skyrmions from liquid crystal topological defect
Mwezi Koni, Fazilah Nothlawala, Vagharshak Hakobyan +3
We propose a spin-orbit strategy for generating dual-wavelength quantum skyrmions, realized either as entangled photon pairs at dual wavelengths or as heralded single-photon states…

Wavelength-adaptive spin-orbit orbital angular momentum management in three-wave mixing
Kiki Dekkers, Mwezi Koni, Vagharshak Hakobyan +5
Here we propose the use of an adjustable liquid crystal spin-orbit device to shape bi-colour structured light to create bimodal states. We demonstrate the proof-of-principle for tw…
