Liquid crystals are a promising candidate for development of active plasmonics due to their large birefringence, low driving threshold, and versatile driving methods. We review recent progress on the interdisciplinary research field of liquid crystal based plasmonics. The research scope of this field is to build the next generation of reconfigurable plasmonic devices by combining liquid crystals with plasmonic nanostructures. Various active plasmonic devices, such as switches, modulators, color filters, absorbers, have been demonstrated. This review is structured to cover active plasmonic devices from two aspects: functionalities and driven methods. We hope this review would provide basic knowledge for a new researcher to get familiar with the field, and serve as a reference for experienced researchers to keep up the current research trends.
由于液晶具有大双折射、低驱动阈值和多样的驱动方法，它们是有源等离子体激元学发展的一个有前途的候选材料。我们回顾了基于液晶的等离子体激元学这一跨学科研究领域的最新进展。该领域的研究范围是通过将液晶与等离子体纳米结构相结合来构建下一代可重构等离子体激元器件。已经展示了各种有源等离子体激元器件，如开关、调制器、滤色器、吸收器等。本综述从功能和驱动方法两个方面涵盖有源等离子体激元器件。我们希望这篇综述能为新研究人员提供基础知识，使其熟悉该领域，并为经验丰富的研究人员提供参考，以跟上当前的研究趋势。
