Control of chirality and directionality of nonlinear metasurface light source via twisting
We demonstrated different singularities of nonlinear susceptibilities in the parameter space of twisted bilayer and tetralayer nonlinear metasurfaces, achieved unidirectional emission with full-Poincaré polarization tunability of second harmonic generation in such metasurfaces.
