Pushing the limits of multifunctional metasurface by deep learning
Pu Peng, Zheyu Fang*Composed of a large number of artificial nanostructures, metasurfaces have found applications in metalenses, structured light generation and optical deflectors through wavefront shaping. After careful design according...
Cathodoluminescence Nanoscopy: State of the Art and Beyond
Zhibo Dang, Yuxiang Chen and Zheyu Fang*Cathodoluminescence (CL) nanoscopy is proven to be a powerful tool to explore nanoscale optical properties, whereby free electron beams achieve a spatial resolution far beyond the diffraction limit...
Twins of Exceptional Points with Opposite Chirality for Non- Hermitian Metasu...
Xiangrong Wu, Xiaofang Zhao, Yihe Lin, Feng Lin*and Zheyu Fang*Exceptional points (EPs) in non-Hermitian systems have recently emerged as an intriguing way to manipulate certain physical processes interacting with the external environmen...
Programmable electron-induced color router array
Cheng Chi, Zhibo Dang, Yongqi Liu, Yuwei Wang, Dewen Cheng*, Zheyu Fang* & Yongtian Wang*The development of color routers (CRs) realizes the splitting of dichromatic components, contributing to the modulation of photon momentum that acts...
轨道角动量复用三维加密全息图
方国全, 林瀚, 王思越, 彭璞, 方哲宇*摘要经过几十年的发展, 全息成像已成为展示信息的成熟光学技术. 然而, 仅通过光的波长和偏振作为信息传递的载体的传统全息技术, 在信息传播的安全性和容量方面存在一定的不足. 将一种新的光学维度, 轨道角动量(orbital...
