Enhanced second harmonic generation in high- all-dielectric metasurfaces with backward frequency conversion

Xu Tu, Siqi Feng, Jiajun Li +4

Here we employ the quasi-bound state in the continuum (quasi-BIC) resonance in all-dielectric metasurfaces for efficient nonlinear processes in consideration of the backward freque…

Efficient photon-pair generation empowered by dual quasi-bound states in the continuum

Tingting Liu, Meibao Qin, Siqi Feng +4

Here we demonstrate the efficient photon-pair generation via spontaneous parametric down conversion from a semiconductor metasurface supporting dual quasi-bound states in the conti…
