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…

Enhanced sum-frequency generation from etchless lithium niobate empowered by dual quasi-bound states in the continuum
Siqi Feng, Tingting Liu, Wenya Chen +2
The miniaturization of nonlinear light sources is central to the integrated photonic platform, driving a quest for high-efficiency frequency generation and mixing at the nanoscale.…
