Abstract: Metasurfaces provide new and promising mechanisms with which to control and manipulate light at the nanoscale. While most metasurfaces are designed to operate in the linear regime, it was recently shown that such metasurfaces may… read more here.

Abstract: When a laser beam is incident on a nonlinear grating with a laterally modulated second-order nonlinear coefficient, nonlinear diffraction of the noncollinear second-harmonic generation (SHG) signal occurs, with Raman–Nath nonlinear diffraction (NRND) being a prominent… read more here.
