Reprogrammable plasmonic topological insulators with ultrafast control
Jian Wei You, Qian Ma, Zhihao Lan +3
Topological photonics has revolutionized our understanding of light propagation, but most of current studies are focused on designing a static photonic structure. Developing a dyna…
Generation and Focusing of Orbital Angular Momentum Based on Polarized Reflectarray at Microwave Frequency
Fengxia Li, Haiyan Chen, Yang Zhou +4
A novel polarized reflectarray is designed, fabricated, and experimentally characterized to show its flexibility and efficiency to control wave generation and focusing of orbital a…
Multiplexing-oriented plasmon-MoS2 hybrid metasurfaces driven by nonlinear quasi bound states in the continuum
Qun Ren, Feng Feng, Xiang Yao +6
Rapid progress in nonlinear plasmonic metasurfaces enabled many novel optical characteristics for metasurfaces, with potential applications in frequency metrology, timing character…
Second-harmonic generation via double topological valley-Hall kink modes in all-dielectric photonic crystals
Zhihao Lan, Jian Wei You, Qun Ren +2
Nonlinear topological photonics, which explores topics common to the fields of topological phases and nonlinear optics, is expected to open up a new paradigm in topological photoni…
Tunable and Dual-broadband Giant Enhancement of SHG and THG in a Highly-engineered Graphene-Insulator-Graphene Metasurface
Jian Wei You, Nicolae C. Panoiu
We demonstrate a novel scheme to dramatically enhance both the second- and third-harmonic generation in a graphene-insulator-graphene metasurface. The key underlying feature of our…
Valley-Hall topological plasmons in a graphene nanohole plasmonic crystal waveguide
J. W. You, Z. Lan, Q. Bao +1
We demonstrate that unidirectional and backscattering immune propagation of terahertz optical waves can be achieved in a topological valley-Hall waveguide made of graphene nanohole…
