“…To holographically shape scalar self-imaging light fields, Fourier holograms can be applied, encoded on a phase-only spatial light modulator (SLM; Holoeye Pluto phase-only SLM, HD display) for far field construction [33,38]. As indicated in figure 1(c), a lens enables the transformation from Fourier to real space of the desired light field.…”

“…More precisely, we combine knowledge on scalar self-imaging light fields with our polarization modulation approach for the desired formation of 3d structured vectorial light fields, namely vectorial self-imaging light fields. Note that further context and studies on our approach are given in [33]. Our approach is based on partially coherent plane wave interference, allowing to tailor polarization in all three spatial dimensions simultaneously.…”

We transfer on-demand structuring of three-dimensional scalar amplitude and phase patterns to polarization-structured, vectorial light fields and its singularities. Our approach allows inheriting non-diffracting as well as self-imaging propagation properties to tailored singular ellipse fields, including self-replicating amplitude, polarization, and singularity configurations. It is experimentally realized by amplitude, phase and polarization modulation of the angular spectrum of the light field. We demonstrate the customization of complex singularity formations embedded in three-dimensionally (3d) tailored vectorial field. Our findings show that embedded networks of polarization singularities can be customized to propagate in a robust way along curved trajectories, creating and annihilating during propagation. This 3d structuring of vectorial singular light fields opens new perspectives for in-depth singularity studies and for advancing applications as optical micro-manipulation and material machining.
