摘要

将光限制在尺寸越来越小的纳米结构中，可以更精确地控制光与物质的相互作用。在第2400223号文章中，Taisuke Ohta及其同事使用光电子发射显微镜演示了介质超表面内体积型光子共振的近场成像。这种成像方法利用远场激发和亚光学波长空间分辨率，为研究介电纳米光子系统中的光-物质相互作用提供了新的途径。

Imaging Photonic Resonances within an All-Dielectric Metasurface via Photoelectron Emission Microscopy

All-Dielectric Metasurfaces

Confinement of light within nanostructures of increasingly smaller sizes has resulted in ever more precise control of light-matter interactions. In article number 2400223, Taisuke Ohta and co-workers demonstrate near-field imaging of volume-type photonic resonances within a dielectric metasurface using photoelectron emission microscopy. This imaging approach, utilizing far-field excitation and sub-optical wavelength spatial resolution, offers a new avenue for examining light–matter interactions within dielectric nanophotonic systems.
