Active control of electromagnetically induced transparency analogue in terahertz metamaterials
Jianqiang Gu,Ranjan Singh,Xiaojun Liu,Xueqian Zhang,Yingfang Ma,Shuang Zhang,Stefan A. Maier,Zhen Tian,Abul Kalam Azad,Hou-Tong Chen,Antoinette J. Taylor,Jiaguang Han,Weili Zhang,Weili Zhang +13 more
TL;DR: This work presents active optical control of metamaterial-induced transparency through active tuning of the dark mode, and opens up the possibility for designing novel chip-scale ultrafast devices that would find utility in optical buffering and terahertz active filtering.
Journal ArticleDOI
Broadband Metasurfaces with Simultaneous Control of Phase and Amplitude
Lixiang Liu,Lixiang Liu,Xueqian Zhang,Xueqian Zhang,Mitchell Kenney,Xiaoqiang Su,Ningning Xu,Chunmei Ouyang,Yunlong Shi,Jiaguang Han,Weili Zhang,Weili Zhang,Shuang Zhang +12 more
TL;DR: By combining the freedom of both the structural design and the orientation of split ring resonator antennas, this work demonstrates terahertz metasurfaces that are capable of controlling both the phase and amplitude profiles over a very broad bandwidth.
Journal ArticleDOI
Broadband Terahertz Wave Deflection Based on C‐shape Complex Metamaterials with Phase Discontinuities
Xueqian Zhang,Zhen Tian,Weisheng Yue,Jianqiang Gu,Shuang Zhang,Jiaguang Han,Weili Zhang,Weili Zhang +7 more
TL;DR: A broadband terahertz wave deflector based on metasurface induced phase discontinuities and a Fresnel zone plate consequently developed from the beam deflector is capable of focusing a broadband terAhertz radiation.
Journal ArticleDOI
A perfect metamaterial polarization rotator
Longqing Cong,Wei Cao,Xueqian Zhang,Zhen Tian,Jianqiang Gu,Ranjan Singh,Jiaguang Han,Weili Zhang +7 more
TL;DR: In this paper, a unique approach to efficiently rotate the linear polarization of terahertz wave in a broadband configuration with tri-layer metasurfaces was proposed, where the Fabry-Perot cavity effect was attributed to the underlying mechanism of high transmittance and polarization rotation.
Journal ArticleDOI
Active graphene–silicon hybrid diode for terahertz waves
Quan Li,Zhen Tian,Xueqian Zhang,Ranjan Singh,Liangliang Du,Jianqiang Gu,Jiaguang Han,Weili Zhang +7 more
TL;DR: A large transmission modulation of 83% is obtained in the graphene–silicon hybrid film, which exhibits tremendous potential for applications in designing broadband terahertz modulators and switchable terAhertz plasmonic and metamaterial devices.
