We present 4D topological textures in (quasi)monochromatic nonparaxial optical lattices that contain all possible polarization ellipses with every combination of ellipticity and orientation in 3D space. These fields span the nonparaxial polarization space (a complex projective plane) and a 4-sphere within specific spatiotemporal regions, forming 4D skyrmionic structures. Constructed from five plane waves with adiabatically varying relative amplitudes, they are experimentally realizable in free space by focusing a temporally variant beam with a high numerical aperture lens.

  1. Optical Skyrmions of Vortex Darkness

    physics.optics 2025-01 conditional novelty 6.0 of 10

    A scalar optical vortex is shown to host a unit-charge transverse-axial polarization skyrmion, arising from the longitudinal field dictated by Gauss's divergence law, and this is verified experimentally.
