Ren Jie Lin,Vin Cent Su,Shuming Wang,Mu Ku Chen,Tsung Lin Chung,Yu Han Chen,Hsin Yu Kuo,Jia Wern Chen,Ji Chen,Ji Chen,Yi Teng Huang,Jung Hsi Wang,Cheng Hung Chu,Pin Chieh Wu,Tao Li,Tao Li,Zhenlin Wang,Shining Zhu,Shining Zhu,Din Ping Tsai,Din Ping Tsai,Din Ping Tsai +21 more
TL;DR: A metalens array made of gallium nitride (GaN) nanoantennas that can be used to capture light-field information and demonstrate a full-colour light- field camera devoid of chromatic aberration is described.
Journal ArticleDOI
Digitalizing Self-Assembled Chiral Superstructures for Optical Vortex Processing.
Peng Chen,Ling-Ling Ma,Wei Duan,Ji Chen,Shi-Jun Ge,Zhi-Han Zhu,Ming-Jie Tang,Ran Xu,Wei Gao,Tao Li,Wei Hu,Yan-qing Lu +11 more
TL;DR: A concept for digitalized chiral superstructures is proposed, which further enables the arbitrary manipulation of reflective geometric phase and may significantly upgrade existing optical apparatus by encoding a specifically designed binary pattern.
Journal ArticleDOI
Stable, high-performance sodium-based plasmonic devices in the near infrared.
Yang Wang,Jianyu Yu,Yifei Mao,Ji Chen,Suo Wang,Hua-Zhou Chen,Yi Zhang,Si-Yi Wang,Xinjie Chen,Tao Li,Lin Zhou,Ren-Min Ma,Shining Zhu,Wenshan Cai,Jia Zhu +14 more
TL;DR: These sodium-based plasmonic devices show stable performance under ambient conditions over a period of several months after packaging with epoxy, indicating that the performance of plasMonic devices can be greatly improved beyond that of devices using noble metals, with implications for applications in plAsmonics, nanophotonics and metamaterials.
Journal ArticleDOI
Spectral tomographic imaging with aplanatic metalens.
Chen Chen,Wange Song,Jia-Wern Chen,Jung-Hsi Wang,Yu Han Chen,Beibei Xu,Mu Ku Chen,Hanmeng Li,Bin Fang,Ji Chen,Hsin Yu Kuo,Shuming Wang,Din Ping Tsai,Shining Zhu,Tao Li +14 more
TL;DR: A metalens-based spectral imaging system with an aplanatic GaN metalens, in which large chromatic dispersion is used to access spectral focus tuning and optical zooming in the visible spectrum, and develops a new imaging technique that advances recent informative optical devices.
