Harmonic Generation in Metal-Insulator and Metal-Insulator-Metal Nanostructures
Mallik M. R. Hussain, Imad Agha, Zhengning Gao +6
We report that the second and third harmonic signal reductions with insulator film surface coverage over a gold substrate gives a measure of the electron density in the spill out v…
Harmonic Generation from Metal-Oxide and Metal-Metal Boundaries
M. Scalora, M. A. Vincenti, D. de Ceglia +7
We explore the outcomes of detailed microscopic models by calculating second- and third-harmonic generation from thin film surfaces with discontinuous free-electron densities. Thes…
Graphene-based perfect optical absorbers harnessing guided mode resonances
M. Grande, M. A. Vincenti, T. Stomeo +8
We numerically and experimentally investigate graphene-based optical absorbers that exploit guided mode resonances (GMRs) achieving perfect absorption over a bandwidth of few nanom…
Graphene-based absorber exploiting guided mode resonances in one-dimensional gratings
M. Grande, M. A. Vincenti, T. Stomeo +8
A one-dimensional dielectric grating, based on a simple geometry, is proposed and investigated to enhance light absorption in a monolayer graphene exploiting guided mode resonances…
Nonlinear Control of Absorption in Graphene-based 1D Photonic Crystal
M. A. Vincenti, D. de Ceglia, M. Grande +2
Perfect, narrow-band absorption is achieved in an asymmetric 1D photonic crystal with a monolayer graphene defect. Thanks to the large third order nonlinearity of graphene and fiel…
Singularity-driven Second and Third Harmonic Generation in a ε-near-zero nanolayer
M. A. Vincenti, D. de Ceglia, A. Ciattoni +1
We show a new path to ε~0 materials without resorting to metal-based metamaterial composites. A medium that can be modeled using Lorentz oscillators usually displays ε=0 crossing p…
