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…
Universal nondiffractive topological spin textures in vortex cores of light and sound
Elena Annenkova, Andrei Afanasev, Etienne Brasselet
We report universal skyrmionic spin textures in the cores of optical and acoustic vortex beams, described within the framework of Laguerre-Gaussian modes. We analytically demonstra…
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…
