Taking into account phase–polarization interactions is crucial for the formation of spatially structured laser beams. The effects that arise in this context can lead to modulation individual field components and transformation overall light field. In study, we investigate impact phase polarization distributions with radial dependencies polar coordinates on longitudinal component beams passing through a transmissive spatial modulator (SLM) based twisted nematic liquid crystals. Although amplitude, phase, distribution transformed behind SLM do not depend azimuthal angle, structure exhibits spiral shape. By utilizing shaped fields projection lithography technique, demonstrate feasibility fabricating microaxicons thin films polarization-sensitive materials. We also show direction twist period microaxicon be controlled by manipulating parameters masks displayed SLM. Furthermore, potential parallel fabrication arrays such microelements. results obtained precise processing photosensitive materials requires taking possible illuminating radiation.

This paper presents a novel method for generating and shaping reverse energy flow through the interference of light fields from minimal number point sources. Until now, has only been observed using complex fields, such as optical vortices or cylindrical vector beams, limiting formation near axis. We demonstrate both analytically numerically that unbounded regions can be achieved with just two sources, positioned asymmetrically at specific angles (e.g., 90 45 degrees) particular polarization states. The results indicate relative enhanced by increasing sources to three four, adjusting their polarization, introducing vortex phase singularity. presence an initially embedded asymmetry in under consideration leads non-uniform distribution spin orbital angular momentum density. Variations state, well introduction singularity, allow changing density while maintaining flow. also explore feasibility implementing obtained sectional diffractive elements, which will enhance efficiency generated compared
