Two-dimensional (2D) materials are extensively used in almost all scientific research areas, from fundamental research to applications. Initially, 2D materials were integrated with conventional non-2D materials having well-established manufacturing methods. Recently, the concept of constructing photonic devices exclusively from 2D materials has emerged. Various devices developed to date have been demonstrated based on monolithic or hetero 2D materials. In this review, photonic devices that solely consist of 2D materials are introduced, including photonic waveguides, lenses, and optical cavities. Exploring photonic devices that are made entirely of 2D materials could open interesting prospects as they enable the thinnest devices possible because of their extraordinarily high refractive index. In addition, unique characteristics of 2D materials, such as high optical anisotropy and spin orbit coupling, might provide intriguing applications.
二维（2D）材料广泛应用于几乎所有科学研究领域，从基础研究到应用。最初，二维材料与具有成熟制造方法的传统非二维材料相结合。最近，仅由二维材料构建光子器件的概念已经出现。迄今为止开发的各种器件都是基于单片或异质二维材料展示的。在这篇综述中，介绍了仅由二维材料组成的光子器件，包括光子波导、透镜和光学腔。探索完全由二维材料制成的光子器件可能会开辟有趣的前景，因为它们因其极高的折射率而能够实现尽可能薄的器件。此外，二维材料的独特特性，如高光光学各向异性和自旋轨道耦合，可能会提供有趣的应用。
