Fig. 4: Transmittance and THG intensity maps.
From: A multi-mode super-fano mechanism for enhanced third harmonic generation in silicon metasurfaces
a Calculated spectral transmittance and (b) THG intensity maps of the metasurface as a function of the nanodisk elliptical diameter dx with perfectly vertical sidewalls. The dashed curve in both maps marks the linear MQ/Fano resonance, which coincides with the maximum of THG in map (b). c, d The same as panel (a, b) but for nanodisks with 1° slanted sidewalls. e Corresponding experimental spectral transmittance and (f) TH amplification maps of the fabricated metasurface
