飞秒激光赋能液晶光子学
Femtosecond laser-empowered liquid crystal photonics
摘要
Abstract
Liquid crystal,as a kind of typical soft material,has unique physical properties and controllable molecular structures,which has become the research frontier in the fields of flexible optoelectronic devices and soft condensed matter physics.The high peak power and short pulse duration characteristics of femtosecond laser combined with the flexible and high-precision two-photon polymerization processing technology provide an effective experimental scheme for the design and manufacture of novel regulatable liquid crystal photonics microstructures to manipulate the linear and nonlinear responses of the liquid crystal molecules.Femtosecond laser-empowered liquid crystal photonics can not only promote the rapid development of soft matter,but also bring new opportunities for the development of optical devices in the future.In this paper,the nonlinear effects in liquid crystals induced by femtosecond laser,the fabrication of liquid crystal elastomers by using femtosecond laser processing technology and the realization of out of plane orientation of liquid crystal molecules by microstructures fabricated by femtosecond laser are reviewed,and the recent research progress of the relevant directions in the field of practical application is also introduced.关键词
