Xue Jiang,Hao Chen,Zeyu Li,Hong-Kuan Yuan,Luyao Cao,Luo Zhenfei,Kun Zhang,Zhihai Zhang,Zhongquan Wen,Li-Guo Zhu,Xun Zhou,Gaofeng Liang,Desheng Ruan,Du Lianghui,Lingfang Wang,Gang Chen +15 more
TL;DR: This work proposes a metalens based on an all-dielectric metasurface with a sub-wavelength unit size of 0.39λ for terahertz wave imaging and experimentally demonstrate its performance in focusing and imaging, and demonstrates the reversibility of the metalens for imaging.
Journal ArticleDOI
Far-field sub-diffraction focusing lens based on binary amplitude-phase mask for linearly polarized light.
Gang Chen,Kun Zhang,Anping Yu,Xianyou Wang,Zhihai Zhang,Yuyan Li,Zhongquan Wen,Chen Li,Luru Dai,Senling Jiang,Feng Lin +10 more
TL;DR: A far-field sub-diffraction lens based on binary amplitude-phase mask was demonstrated under illumination of linearly polarized plane wave at wavelength 632.8 nm, which was super-oscillatory and has small sidelobes and wide field of view.
Journal ArticleDOI
Super-oscillatory focusing of circularly polarized light by ultra-long focal length planar lens based on binary amplitude-phase modulation.
Gang Chen,Yuyan Li,Anping Yu,Zhongquan Wen,Luru Dai,Li Chen,Zhihai Zhang,Senlin Jiang,Kun Zhang,Xianyou Wang,Feng Lin +10 more
TL;DR: A far-field sub-diffraction point-focusing lens based on binary phase and amplitude modulation with ultra-long focal length 252.8 μm and small numerical aperture with great potential applications in far- field super-resolution microscopy, ultra-high-density optical storage and nano-fabrication is reported.
