Journal ArticleDOI
Metasurface orbital angular momentum holography
Haoran Ren,Haoran Ren,Gauthier Briere,Xinyuan Fang,Peinan Ni,Rajath Sawant,Sébastien Héron,Sébastien Chenot,Stéphane Vézian,Benjamin Damilano,Virginie Brandli,Stefan A. Maier,Patrice Genevet +12 more
TL;DR: The authors design metasurface holograms consisting of GaN nanopillars with discrete spatial frequency distributions allowing the reconstruction of distinctive orbital angular momentumdependent holographic images.
Journal ArticleDOI
Self-powered spectrum-selective photodetectors fabricated from n-ZnO/p-NiO core–shell nanowire arrays
TL;DR: In this paper, a self-powered, highly spectrum-selective photodetectors have been fabricated from n-ZnO/p-NiO core-shell nanowire arrays.
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
Metasurface integrated Vertical Cavity Surface Emitting Lasers for programmable directional lasing emissions
Yiyang Xie,Peinan Ni,Qiuhua Wang,Qiang Kan,Gauthier Briere,Pei-Pei Chen,Zhuang-Zhuang Zhao,Alexandre Delga,Haoran Ren,Hongda Chen,Chen Xu,Patrice Genevet +11 more
TL;DR: It is shown that the monolithic integration of dielectric metasurfaces with VCSELs enables remarkable arbitrary control of the laser beam profiles, including self-collimation, Bessel and Vortex lasers, with high efficiency.
