Structured light

Andrew Forbes et al.

Summary: Recent efforts have focused on controlling the structure of light in all its degrees of freedom and dimensions, pushing the limits of structured light and expanding its potential. Beyond traditional orbital angular momentum, two-dimensional fields, qubits and biphotons, and linear optical manipulation.

Self-imaging vectorial singularity networks in 3d structured light fields

Ramon Droop et al.

Summary: This research transfers the on-demand structuring of three-dimensional scalar light field patterns to polarization-structured vectorial light fields and its singularities. The customization of complex singularity formations embedded in three-dimensionally tailored vectorial field is experimentally realized through modulation of the light field's amplitude, phase, and polarization. The study shows that polarization singular networks can be customized to propagate robustly along curved trajectories, creating and annihilating during propagation.
