Researchers Generate Single-Photon Skyrmions Using Nanophotonic Structures
Scientists have demonstrated a method to create single-photon states with topological textures by mapping the total angular momentum of light in nanophotonic near-field environments. The approach, reported in eLight, uses plasmonic nanostructures to couple spin and orbital angula…
