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 WBs.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 WBs through patterned nematic LC optical elements,patterned cholesteric LC optical ele-ments,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.
