Lei Wang,Xiao Wen Lin,Wei Hu,Guang Hao Shao,Peng Chen,Lan Ju Liang,Biaobing Jin,Pei Heng Wu,Hao Qian,Yi Nong Lu,Xiao Liang,Zhigang Zheng,Yan-qing Lu +12 more
TL;DR: In this article, a few-layer porous graphene is employed as an electrode with a transmittance of more than 98% and a subwavelength metal wire grid is utilized as an integrated high-efficiency electrode and polarizer.
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
Meta-q-plate for complex beam shaping
Wei Ji,Chun-Hong Lee,Peng Chen,Wei Hu,Yang Ming,Lijian Zhang,Tsung-Hsien Lin,Vladimir G. Chigrinov,Yan-qing Lu +8 more
TL;DR: Meta-q-plate featured by arbitrarily space-variant optical axes is proposed and demonstrated via liquid crystal photoalignment based on a polarization-sensitive alignment agent and a dynamic micro-lithography system to enhance the capability of beam shaping.
Journal ArticleDOI
Arbitrary and reconfigurable optical vortex generation: a high-efficiency technique using director-varying liquid crystal fork gratings
TL;DR: In this article, a high efficiency technique for optical vortex (OV) generation is proposed and demonstrated based on liquid crystal fork gratings with space-variant azimuthal orientations, which are locally controlled via polarization sensitive alignment layers.
Journal ArticleDOI
Liquid-Crystal-Mediated Geometric Phase: From Transmissive to Broadband Reflective Planar Optics
TL;DR: Combining the geometric phase with structured LC materials offers a satisfactory platform for planar optics with desired functionalities and drastically extends exceptional applications of ordered soft matter.
