Second-harmonic generation in plasmonic waveguides with nonlocal response and electron spill-out
Ahsan Noor, Muhammad Khalid, Federico De Luca +4
Plasmonic waveguides provide an integrated platform to develop efficient nanoscale ultrafast photonic devices. Theoretical models that describe nonlinear optical phenomena in plasm…

Influence of the electron spill-out and nonlocality on gap-plasmons in the limit of vanishing gaps
M. Khalid, O. Morandi, E. Mallet +4
We study the effect of electron spill-out and of nonlocality on the propagation of light inside a gap between two semi-infinite metallic regions. We compare the predictions of a lo…

Enhancing second-harmonic generation with electron spill-out at metallic surfaces
Muhammad Khalid, Cristian Ciracì
Second-order nonlinear optical processes do not manifest in the bulk of centrosymmetric materials, but may occur in the angstroms-thick layer at surfaces. At such length-scales, qu…
