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…
Topological valley plasmon transport in bilayer graphene metasurfaces for sensing applications
Yupei Wang, Jian Wei You, Zhihao Lan +1
Topologically protected plasmonic modes located inside topological bandgaps are attracting increasing attention, chiefly due to their robustness against disorder-induced backscatte…
Local orbital-angular-momentum dependent surface states with topological protection
Menglin L. N. Chen, Li Jun Jiang, Zhihao Lan +1
Chiral surface states along the zigzag edge of a valley photonic crystal in the honeycomb lattice are demonstrated. By decomposing the local fields into orbital angular momentum (O…
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…
First-principle calculation of Chern number in gyrotropic photonic crystals
Ran Zhao, Guo-Da Xie, Menglin L. N. Chen +3
As an important figure of merit for characterizing the quantized collective behaviors of the wavefunction, Chern number is the topological invariant of quantum Hall insulators. Che…
