Enhanced third-harmonic generation empowered by doubly degenerate quasi-bound states in the continuum
Tingting Liu, Meibao Qin, Jumin Qiu +6
Recent advancements in nonlinear nanophotonics are driven by the exploration of sharp resonances within high-index dielectric metasurfaces. In this work, we leverage doubly degener…
Enhanced third-harmonic generation and degenerate four-wave mixing in an all-dielectric metasurfaces via Brillouin zone folding-induced bound states in the continuum
Meibao Qin, Feng Wu, Tingting Liu +2
Bound states in the continuum (BICs) exhibit significant electric field confinement capabilities and have recently been employed to enhance nonlinear optics response at the nanosca…
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…
