A Dynamical Model of Harmonic Generation in Centrosymmetric Semiconductors
M. Scalora, M. A. Vincenti, D. de Ceglia +4
We study second and third harmonic generation in centrosymmetric semiconductors at visible and UV wavelengths in bulk and cavity environments. Second harmonic generation is due to…
Experimental demonstration of a novel bio-sensing platform via plasmonic band gap formation in gold nano-patch arrays
Marco Grande, Maria Antonietta Vincenti, Tiziana Stomeo +9
We discuss the possibility of implementing a novel bio-sensing platform based on the observation of the shift of the leaky surface plasmon mode that occurs at the edge of the plasm…
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…
Harmonic generation and energy transport in dielectric and semiconductors at visible and UV wavelengths: the case of GaP
Vito Roppo, Neset Akozbek, Domenico de Ceglia +2
We study inhibition of absorption, transparency, energy and momentum transport of the inhomogeneous component of harmonic pulses in dielectrics and semiconductors, at visible and U…
Enhanced second harmonic generation from resonant GaAs gratings
D. de Ceglia, G. D'Aguanno, N. Mattiucci +2
We study second harmonic generation in nonlinear, GaAs gratings. We find large enhancement of conversion efficiency when the pump field excites the guided mode resonances of the gr…
