Abstract

We have studied the formation of energy optical flows with phase singularities using a biaxial crystal during the propagation of light along its optical axes. We have expanded the theoretical foundations for forming a conoscope image in a biaxial crystal, as developed by Berry, to cover the case of arbitrary orientation of polarization elements. It has been shown that increasing the thickness of the crystal enhances the intensity gradient in the phase singularity, thereby enabling more reliable trapping and manipulation of nanoparticles. Reducing the scale of the phase singularity results in a sharper intensity distribution within the singularity, allowing for the capture of smaller nanoparticles.
