Quantum Conductivity for Metal-Insulator-Metal Nanostructures
Joseph W. Haus, Domenico de Ceglia, Maria Antonietta Vincenti +1
We present a methodology based on quantum mechanics for assigning quantum conductivity when an ac field is applied across a variable gap between two plasmonic nanoparticles with an…
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…
Tailoring absorption in metal gratings with resonant ultra-thin bridges
M. A. Vincenti, D. de Ceglia, M. Grande +2
We present a theoretical analysis of the effects of short range surface plasmon polariton excitation on sub-wavelength bridges in metal gratings. We show that localized resonances…
Harmonic Generation in Multi-Resonant Plasma Films
M. A. Vincenti, D. de Ceglia, J. W. Haus +1
We investigate second and third harmonic generation in a slab of material that displays plasma resonances at the pump and its harmonic frequencies. Near-zero refractive indices and…
Second harmonic double resonance cones in dispersive hyperbolic metamaterials
Domenico de Ceglia, Maria Antonietta Vincenti, Salvatore Campione +3
We study the formation of second harmonic double-resonance cones in hyperbolic metamaterials. An electric dipole on the surface of the structure induces second harmonic light to pr…
Spontaneous and Stimulated Raman Scattering near Metal Nanostructures in the Ultrafast, High-Intensity regime
M. Scalora, M. A. Vincenti, D. de Ceglia +2
The inclusion of atomic inversion in Raman scattering can significantly alter field dynamics in plasmonic settings. Our calculations show that large local fields and femtosecond pu…
