Reprogrammable meta-hologram for optical encryption.
Geyang Qu,Wenhong Yang,Qinghai Song,Qinghai Song,Yilin Liu,Cheng-Wei Qiu,Jiecai Han,Din Ping Tsai,Shumin Xiao,Shumin Xiao +9 more
TL;DR: A re-programmable metasurface that can produce arbitrary holographic images for optical encryption and decrypted and it is hoped that this work paves a more promising way to optical information encryption and authentication.
Journal ArticleDOI
Sculpting nanoparticle dynamics for single-bacteria-level screening and direct binding-efficiency measurement
Yue Shi,S. Xiong,Yi Zhang,Lip Ket Chin,Yicai Chen,Jing Zhang,Tong Zhang,Wee Ser,A. Larrson,S. H. Lim,J. H. Wu,Tianfeng Chen,Zhen Yang,Yi Hao,Bo Liedberg,P. H. Yap,K. Wang,Din Ping Tsai,Cheng-Wei Qiu,Cheng-Wei Qiu,Ai Qun Liu,Ai Qun Liu +21 more
TL;DR: An optofluidic lattice is used to achieve controllable multi-particle hopping and demonstrate single-bacteria-level screening and measurement of binding efficiency of biological binding agents through particle-enabled bacteria hopping.
Journal ArticleDOI
Integrated plasmonic metasurfaces for spectropolarimetry
Wei Ting Chen,Peter Török,Matthew R. Foreman,Chun Yen Liao,Wei-Yi Tsai,Pei Ru Wu,Din Ping Tsai,Din Ping Tsai +7 more
TL;DR: In this article, the authors demonstrate a chip-scale device suitable for simultaneous polarization and spectral measurements through use of six integrated plasmonic metasurfaces (IPMs), which diffract light with a given polarization state and spectral component into well-defined spatial domains.
Journal ArticleDOI
Toroidal lasing spaser.
Yao-Wei Huang,Wei Ting Chen,Pin Chieh Wu,Vassili A. Fedotov,Nikolay I. Zheludev,Din Ping Tsai,Din Ping Tsai +6 more
TL;DR: Coupling optical gain medium with high Q-factor toroidal resonance mode can enhance the single pass amplification to up to 65 dB, offering an opportunity of creating the “toroidal” lasing spaser, a source of coherent optical radiation that is fueled by toroidal plasmonic oscillations in the nanostructure.
Journal ArticleDOI
A Flat Lens with Tunable Phase Gradient by Using Random Access Reconfigurable Metamaterial
Weiming Zhu,Qinghua Song,Libin Yan,Wu Zhang,Pin Chieh Wu,Lip Ket Chin,Hong Cai,Din Ping Tsai,Zhongxiang Shen,Tianwei Deng,Sing Kwong Ting,Yuandong Gu,Guo-Qiang Lo,Dim-Lee Kwong,Zhenchuan Yang,Ru Huang,Ai Qun Liu,Nikolay I. Zheludev +17 more
TL;DR: The first demonstration of an optofluidic metamaterial is reported where resonant properties of every individual metamolecule can be continuously tuned at will using a microfluidic system.
