Parametric wave interaction in quadratic crystal with randomized distribution of ferroelectric domains
Ksawery Kalinowski, Vito Roppo, Tadeusz Łukasiewicz +3
We study the parametric wave interaction in qua- dratic nonlinear media with randomized distribution of the ferroelectric domains. In particular, we discuss properties of second an…
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…
Harmonic Generation in Metallic, GaAs-Filled Nanocavities in the Enhanced Transmission Regime at Visible and UV Wavelengths
M. A. Vincenti, D. de Ceglia, V. Roppo +1
We have conducted a theoretical study of harmonic generation from a silver grating having slits filled with GaAs. By working in the enhanced transmission regime, and by exploiting…
Third Harmonic Generation at 223nm in the Metallic Regime of GaP
V. Roppo, J. Foreman N. Akozbek, M. A. Vincenti +1
We demonstrate second and third harmonic generation from a GaP substrate 500μm thick. The second harmonic field is tuned at the absorption resonance at 335nm, and the third harmoni…
Generation Efficiency of the Second Harmonic Inhomogeneous Component
V. Roppo, F. Raineri, C. Cojocaru +5
In this letter we experimentally demonstrate second harmonic conversion in the opaque region of a GaAs cavity with efficiencies of the order of 0.1% at 612nm, using 3ps pump pulses…
Second and Third Harmonic Generation in Metal-Based Nanostructures
M. Scalora, M. A. Vincenti, D. de Ceglia +4
We present a new theoretical approach to the study of second and third harmonic generation from metallic nanostructures and nanocavities filled with a nonlinear material, in the ul…
