石墨烯是以蜂窝状晶格排列的碳原子的单层：原子薄、轻、灵活、机械强度强、视觉透明、电可调，如果掺杂的话还具有很高的导电性。石墨烯还与从微波到紫外线的光发生强烈的相互作用，跨越至少五个数量级的波长。这种强烈的光-石墨烯相互作用，加上其特殊的电子和机械性能，使石墨烯成为各种光子应用的潜在候选者。本文首先讨论了单电子近似下光-石墨烯相互作用的物理过程，然后讨论了载流子集体振荡的光激发，即石墨烯中的等离子体激子。然后介绍了基于上述两种不同的光-石墨烯相互作用机制在不同波长范围内工作的各种光子器件，例如光电探测器、光调制器、电磁波屏蔽、陷波滤光器和线性偏振器。最后，我们讨论了石墨烯光子学研究的未来方向。
Graphene is a monolayer of carbon atoms arranged in a honey-comb lattice: atomically thin, light, flexible, mechanically strong, visually transparent, electrically tunable, and highly conductive if doped. Graphene also interacts with light strongly from the microwave range to the ultraviolet, spanning wavelengths of at least five orders of magnitude. Such strong light-graphene interaction, together with its exceptional electronic and mechanical properties, makes graphene a promising candidate for various photonic applications. The early part of this paper addresses the physics of light-graphene interaction under a single-electron approximation, followed by a discussion of light excitation of collective oscillations of the carriers, i.e., plasmons in graphene. A variety of photonic devices operating in different wavelength ranges based on the two different light-graphene interaction mechanisms discussed above, such as photodetectors, optical modulators, electromagnetic wave shieldings, notch filters, and linear polarizers are then covered. Finally, we discuss the future directions for graphene photonics research.
