Impact of surface charge depletion on the free electron nonlinear response of heavily doped semiconductors
Federico De Luca, Cristian Ciracì
We propose surface modulation of the equilibrium charge density as a technique to control and enhance, via an external static potential, the free electron nonlinear response of hea…
Nanogap-Enhanced Infrared Spectroscopy with Template-Stripped Wafer-Scale Arrays of Buried Plasmonic Cavities
Xiaoshu Chen, Cristian Ciracì, David R. Smith +1
We have combined atomic layer lithography and template stripping to produce a new class of substrates for surface-enhanced infrared absorption (SEIRA) spectroscopy. Our structure c…
Second-harmonic generation from singular metasurfaces
Fan Yang, Cristian Ciracì
We present a theoretical study of second-harmonic generation from a singular metasurface. The singular metasurfaces strongly interact with the incident light, where the large field…
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…
