Nonlocal Metasurface Lens for Long-Wavelength Infrared Radiation
Federico De Luca, Sriram Guddala, Michele Cotrufo +3
Dielectric metasurfaces are structured thin films with thickness smaller than the wavelength that aim at replacing and enhancing conventional bulk optical components by structuring…
Origin of optical nonlinearity in plasmonic semiconductor nanostructures
Andrea Rossetti, Huatian Hu, Tommaso Venanzi +15
The development of nanoscale nonlinear elements in photonic integrated circuits is hindered by the physical limits to the nonlinear optical response of dielectrics, which requires…
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…
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…
