【摘要】：蓝相液晶是一种三维手性自组装软超结构材料,具有光学各向同性,选择性反射波长,快速响应等优秀特性,无论在显示还是光子器件的应用上都具有良好的发展前景,吸引了研究人员的大量关注。近十年关于蓝相液晶显示领域的研究与工程或应用发展迅猛,于此同时催生了其在光子学这个后显示领域的研究。面对来自国际上其他先进国家的竞争与压力,中国大陆的学者们奋勇迎接,经过短短数年的发展获得了一批有显示度的成果,在国内外的优秀期刊上报道了一系列富含学术性和实用性的工作。具备高热稳定性与显著电光调制特性的新型蓝相液晶材料及其光子学器件,如衍射光栅、相位调制器、透镜、激光以及光衰减器等,相继被开发出。本文追逐这些前辈留下的脚印,从材料制备、性能到光子器件设计、应用进行了概括性的回顾,旨在通过此综述激发出蓝相液晶在非显示光子学应用领域更多的研究灵感;若能起到进一步促进该领域发展的作用,笔者将感到幸甚之至!
[Abstract]:Blue-phase liquid crystal is a kind of three-dimensional chiral self-assembled soft superstructure material. It has many excellent properties such as optical isotropy, selective reflection wavelength, fast response and so on. It has a good development prospect in both the display and the application of photonic devices. Has attracted a lot of attention from researchers. In the last decade, the research and engineering of blue-phase liquid crystal display (blue-phase liquid crystal display) has developed rapidly. In the face of competition and pressure from other advanced countries in the world, scholars from mainland China have come forward to welcome the research in the field of photonics. After a few short years of development, we have achieved a number of results with the degree of display. A series of academic and practical work have been reported in excellent journals at home and abroad. Novel blue-phase liquid crystal materials with high thermal stability and remarkable electro-optic modulation properties and their photonics devices such as diffraction gratings, phase modulators, lenses, are reported. Lasers and optical attenuators have been developed one after another. This paper reviews the applications of these predecessors, from material fabrication, performance to photonic device design. The purpose of this review is to inspire more research inspiration of blue liquid crystal in the application of non-display photonics. If it can further promote the development of this field, I would be very fortunate!
