摘　　要：二维材料由于其独特的结构与物理性质具有广阔的应用潜力,在光子学、光电子学、电子学等许多方面已经取得了很大的进展.最近,大数据、光网络、微型光开关等方面的应用需求直接或间接促进了二维材料非线性光学性质方面的研究工作.本文综述了二维材料(包括单层、少层和悬浮液等)的非线性光学性质研究进展:首先简单介绍了几种常见的二维材料(石墨烯、过渡金属硫族化合物、黑磷等)和非线性光学的基本理论,然后主要介绍了二维材料在不同非线性效应(参量过程包括二次谐波、三次谐波和四波混频等,非参量过程包括饱和吸收、双/多光子吸收和非线性折射等)中的发展现状,并在相应部分对这些微纳材料在非线性光学领域的应用前景和未来可能的研究方向进行了展望.Two-dimensional materials have broad potential application because of their unique structures and physical properties,and have made great progress in photonics,optoelectronics,electronics,and many other aspects.Recently,the application requirements of big data,optical networks,and micro-optical switches have directly or indirectly promoted research work on nonlinear optical properties of two-dimensional materials.In this paper,the research progress of nonlinear optical properties of two-dimensional materials(including single layer,few layers and suspension) is reviewed.Firstly,several common two-dimensional materials(graphene,transition metal chalcogenides,black phosphorus,etc.)and the basic theories of nonlinear optics are briefly introduced,and then different nonlinear optical effects(parametric processes including second harmonic,third harmonic and four-wave mixing;non-parametric processes including saturable absorption,two/multi-photon absorption and nonlinear refraction) of the two-dimensional materials are mainly stated,and the application prospects and probable research directions of these micro-nano materials in the field of nonlinear optics are forecasted in each part.
