Vector vortex beams (VVBs) have gained significant attention in both classical and quantum optics. Liquid crystal (LC) has emerged as a versatile tool for manipulating VVBs, with functions and applications of typical LC devices for controlling space-variant polarized vortex light discussed in recent studies. Additionally, LC-based novel optical applications in the field of quantum information are also reviewed.
Vector vortex beams (VVBs) have attracted significant attention in both classical and quantum optics. Liquid crystal (LC), beyond its applications in information display, has emerged as a versatile tool for manipulating VVBs. In this review, we focus on the functions and applications of typical LC devices in recent studies on controlling the space-variant polarized vortex light. Manipulation of VVBs through patterned nematic LC optical elements, patterned cholesteric LC optical elements, self-assembled defects, and LC spatial light modulators is discussed separately. Moreover, LC-based novel optical applications in the field of quantum information are reviewed.
