摘要

液晶是一类具有自组装和刺激响应特性的软物质，其作为当今主流信息显示技术的依托材料而备受瞩目。伴随着液晶理论与技术的发展与革新，人们对这类材料的理解不断加深。近年来，基于光取向技术对液晶微结构的灵活操控，液晶研究逐渐从传统显示领域向更加前沿的液晶光子学领域过渡。在平面光学元件、结构光场、全光互连、模分复用光通信等领域展现出蓬勃的生机。本文综述了南京大学液晶与光子技术研究中心在光取向液晶微结构及其光子元件领域的最新进展，具体讨论了多层级液晶畴构筑、光寻址液晶调光技术、光通信与太赫兹液晶元件。

Abstract

Liquid crystal (LC) is a kind of functional soft matter featured by self-assembly and stimuli responsiveness. It is widely known as a fundamental material for current mainstream information display industry. With the development and innovation of LC theory and technology

understanding on such a material system has been significantly extended. Recently

the manipulation of LC microstructures has been flexibly enabled

via

a photoalignment technique

and the research focus has been gradually transitioned from traditional displays to advanced LC photonics. It is expected to provide great opportunities in the fields of planar optics

structured light fields

optical cross connection

and mode division multiplexing optical communications. This review presents the latest works of the Research Center for Liquid Crystal and Photonics of Nanjing University in the field of photoalignment-enabled LC microstructures and photonic applications. To be specific

LC hierarchical architectures

optically addressed spatial light modulators

and LC telecom/terahertz elements are separately discussed.
