Second Harmonic Generation in Deeply Sub-Wavelength Waveguides
V. Roppo, M. A. Vincenti, D. de Ceglia +1
We theoretically investigate second harmonic generation in extremely narrow, sub-wavelength semiconductor and dielectric waveguides. We discuss a novel guiding mechanism characteri…

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…
