A multi-mode super-fano mechanism for enhanced third harmonic generation in silicon metasurfaces
Abstract We present strong enhancement of third harmonic generation in an amorphous silicon metasurface consisting of elliptical nano resonators. We show that this enhancement originates from a new type of multi-mode Fano mechanism. These ‘Super-Fano’ resonances are investigated numerically in great...
