Overview of soft-photonic topological structures
摘要
Abstract
The distinct states formed by introducing topology into liquid crystal micro-nano photonic systems are referred to as soft-photonic topological structures.Liquid crystals,as an anisotropic soft material,provide an excellent landscape for constructing topological structures in various dimensions.The unique optoelectronic properties of liquid crystals allow topological structures,functioned as quasi-particles,to be optically observed,spatially reconstructed,and microscopically manipulated.With ongoing research,the methods for fabricating soft-photonic topological structures in liquid crystals are continuously improving,with increasing precision,completeness of topological characteristic number,and more potential applications,such as optical soliton control,light information integration,and light-controlled particle motion.This review starts from homotopy theory,introducing and illustrating how to construct two distinct types of topological bodies in liquid crystals and their corresponding dynamic control as response to external stimulus.It then discusses the uniqueness of topological structures in soft liquid crystals,exploring how liquid crystal topological motifs permeate various research fields and their notable applications.Finally,the review gives a summary as well as a brief discussion on future possibilities for unusual manipulating and more complex system for constructing the topological motifs.关键词
