Abstract:Optical field manipulation,as a core method for manipulating beams,provides a key technical pathway for generating complex optical fields and expanding their functions through precise control over dimensions such as amplitude,phase,polarization,mode,and wavelength.Leveraging the dielectric and optical anisotropic properties,liquid crystal (LC)materials,combined with LC photoalignment technology to achieve spatial programming of molecular alignment,exhibit unique advantages of dynamic tunability and high integration in multi-dimensional light field modulation.This paper systematically analyzes the modulation mechanisms of LCs for dimensions including phase,polarization,amplitude,mode,and wavelength of the optical field,discusses the modulation methods of LC materials for structural beams such as Airy beams,Bessel beams,phase vortex beams,and vector vortex beams,and elaborates on the latest research progress in dynamic tuning of light field dimensions by LCs.
Key Words: optical field manipulation; liquid crystals;photoalignment technology; structural beams
