石墨烯因其优异的光学和电学性能,及其与硅基半导体工艺的兼容性,而备受学术界和工业界的广泛关注。作为一种独特的二维原子晶体材料,石墨烯有着优异的机械性能、超高的热导率和载流子迁移率、超宽带的光学响应谱及极强的非线性光学特性,使其在新型光学和光电器件领域具有得天独厚的优势。一系列基于石墨烯的新型光电器件先后被研制出,已显示出优异的性能和良好的应用前景。本文将介绍石墨烯光学性质、与光的相互作用以及提高方法,并给出其在光子和光电子器件领域的应用,分析了这些器件所使用的结构及特点,重点阐述了在全内反射结构下,石墨烯与光相互作用的增强及其偏振依赖性质,及其利用该偏振依赖性质在光学传感、光存储等方面的应用,以及在细胞传感方面的重要发现。最后对石墨烯光学性质及其应用的现状进行了总结和展望。
Graphene has attracted much attention in the academic and industrial fields because of its compatibility with silicon based semiconductor technology. As a unique two-dimensional atomic crystalmaterial, graphene has excellent mechanical properties, high thermal conductivity and carrier mobility, ultra wideband response spectrum and strong nonlinear optical properties, which makes the graphene have advantage in the field of emerging optical and optoelectronic devices. A series of new optoelectronic devices based on graphene have been developed with excellent performance and application prospects. In this paper, we introduced optical properties of graphene, the interaction between graphene and light, and the application in photonic and optoelectronic devices in the field. We also analyzed the structure and characteristics of these new graphene-based devices. We put emphasis on the total internal reection structure, which enhances the interaction between graphene and light. At the same time, we discussed the polarization dependent properties of graphene under the total internal reflection structure, and its application in optical sensing, optical storage and so on with the polarization dependent properties, as well as important discoveries in cell sensing aspects. Finally, the optical properties of graphene and its applications are summarized and prospected.
