Journal ArticleDOI
Independent phase modulation for quadruplex polarization channels enabled by chirality-assisted geometric-phase metasurfaces
Yueyi Yuan,Kuang Zhang,Badreddine Ratni,Qinghua Song,Xumin Ding,Qun Wu,Shah Nawaz Burokur,Patrice Genevet +7 more
TL;DR: The concept of chirality-assisted phase is introduced as a degree of freedom, which could decouple the two co-polarized outputs, and thus be an alternative solution for designing arbitrary modulated-phase metasurfaces with distinct wavefront manipulation in all four CP output channels.
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.
Journal ArticleDOI
Ptychography retrieval of fully polarized holograms from geometric-phase metasurfaces.
Qinghua Song,Arthur Baroni,Rajath Sawant,Peinan Ni,Virginie Brandli,Sébastien Chenot,Stéphane Vézian,Benjamin Damilano,Philippe De Mierry,Samira Khadir,Patrick Ferrand,Patrice Genevet +11 more
TL;DR: A general method relying on pixelated metasurfaces that enables wavefront shaping with arbitrary output polarization, allowing full utilization of polarization channels is demonstrated.
Journal ArticleDOI
Water-Resonator-Based Metasurface: An Ultrabroadband and Near-Unity Absorption
Qinghua Song,Qinghua Song,Wu Zhang,Wu Zhang,Pin Chieh Wu,Weiming Zhu,Zhongxiang Shen,Peter Han Joo Chong,Qing Xuan Liang,Zhenchuan Yang,Yi Long Hao,Hong Cai,Haifeng Zhou,Yuandong Gu,Guo-Qiang Lo,Din Ping Tsai,Tarik Bourouina,Yamin Leprince-Wang,Ai Qun Liu +18 more
TL;DR: In this paper, the authors demonstrated a soft water-resonator-based metasurface, which functions as an active absorbing material across an ultrabroadband range of Ku, K, and Ka bands.
Journal ArticleDOI
Plasmonic topological metasurface by encircling an exceptional point.
TL;DR: In this article, the three main mechanisms used to conceive optical metasurfaces have been discussed: Resonant scattering, guided mode propagation phase, and orientation-dependent phase retardation.
