Si metasurface supporting multiple quasi-BICs for degenerate four-wave mixing

Si metasurface supporting multiple quasi-BICs for degenerate four-wave mixing

Dielectric metasurfaces supporting quasi-bound states in the continuum (qBICs) enable high field enhancement with narrow-linewidth resonances in the visible and near-infrared ranges. The resonance emerges when distorting the meta-atom’s geometry away from a symmetry-protected BIC condition and, usua...
