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…
Comparison between the linear and nonlinear homogenization of graphene and silicon
Qun Ren, J. W. You, N. C. Panoiu
In this paper, we use a versatile homogenization approach to model the linear and nonlinear optical response of two metasurfaces: a plasmonic metasurface consisting of a square arr…
Large enhancement of the effective second-order nonlinearity in graphene metasurfaces
Qun Ren, J. W. You, N. C. Panoiu
Using a powerful homogenization technique, one- and two-dimensional graphene metasurfaces are homogenized both at the fundamental frequency (FF) and second harmonic (SH). In both c…
