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…
Four-wave Mixing of Topological Edge Plasmons in Graphene Metasurfaces
Jian Wei You, Zhihao Lan, Nicolae C. Panoiu
We study topologically-protected four-wave mixing (FWM) interactions in a plasmonic metasurface consisting of a periodic array of nanoholes in a graphene sheet, which exhibits a wi…
Nonlinear one-way edge-mode interactions for frequency mixing in topological photonic crystals
Zhihao Lan, Jian Wei You, Nicolae C. Panoiu
Topological photonics aims to utilize topological photonic bands and corresponding edge modes to implement robust light manipulation, which can be readily achieved in the linear re…
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…
Plasmon-induced nonlinearity enhancement and homogenization of graphene metasurfaces
Jian Wei You, Nicolae C. Panoiu
We demonstrate that the effective third-order nonlinear susceptibility of a graphene sheet can be enhanced by more than two orders of magnitude by patterning it into a graphene met…
Analysis of the interaction between classical and quantum plasmons via FDTD-TDDFT method
Jian Wei You, Nicolae C. Panoiu
A powerful hybrid FDTD--TDDFT method is used to study the interaction between classical plasmons of a gold bowtie nanoantenna and quantum plasmons of graphene nanoflakes (GNFs) pla…
