Abstract Interaction between light and materials is essential in the physics underlying all optical devices, including light emitting devices such as light emitting diodes and lasers, photo-voltaic devices, and photo-synthesis systems. The demand for higher light utilization efficiency is becoming increasingly important for advanced optical devices. This is because, when feature size is smaller than the incident light wavelength, photons cannot couple with devices efficiently. In this paper, we review recent progress regarding a unique phenomenon at the nano scale and its applications. First, we summarize the development of light–matter interactions at the nano-scale. Second, we review recent theoretical works focusing on optical near fields in which unique phenomena arise from non-uniform optical fields. We then review several recent developments based on the near-field effect, including artificial photosynthesis and near-field etching for realization of angstrom-scale fattened surfaces. Finally, we discuss the future outlook for these technologies.

基于非均匀光近场的纳米级化学反应及其应用

摘要 光与材料之间的相互作用在所有光学器件（包括发光二极管和激光器等发光器件、光伏器件和光合作用系统）的物理基础中都是必不可少的。对于先进的光学设备，对更高光利用效率的需求变得越来越重要。这是因为，当特征尺寸小于入射光波长时，光子不能有效地与器件耦合。在本文中，我们回顾了有关纳米级独特现象及其应用的最新进展。首先，我们总结了纳米级光-物质相互作用的发展。其次，我们回顾了最近关于光学近场的理论工作，其中非均匀光场产生了独特的现象。然后，我们回顾了基于近场效应的几项最新进展，包括人工光合作用和近场蚀刻，以实现埃级增肥表面。最后，我们讨论了这些技术的未来前景。
