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…
Giant enhancement of the transverse magneto-optical Kerr effect in etchless bismuth-substituted yttrium iron garnet empowered by quasi-bound states in the continuum
Qin Tang, Dandan Zhang, Shuyuan Xiao +5
Here, we propose an etchless bismuth-substituted yttrium iron garnet layer assisted by a one-dimensional resonant grating waveguide to enhance transverse magneto-optical Kerr effec…
Edge detection imaging by quasi-bound states in the continuum
Tingting Liu, Jumin Qiu, Lei Xu +6
Optical metasurfaces have revolutionized analog computing and image processing at sub-wavelength scales with faster speed and lower power consumption. They typically involve spatia…
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…
