High-efficiency infrared upconversion imaging with nonlinear silicon metasurfaces empowered by quasi-bound states in the continuum
Tingting Liu, Jumin Qiu, Meibao Qin +6
Infrared imaging is indispensable for its ability to penetrate obscurants and visualize thermal signatures, yet its practical use is hindered by the intrinsic limitations of conven…
Quasi-Bound States in the Continuum-Induced Second Harmonic Generation Enhancement in High- Triple Dielectric Nanoresonators
Xu Tu, Meibao Qin, Huifu Qiu +4
High- optical nanocavities are fundamental to modern optics and photonics, enabling enhanced light-matter interactions. Previous studies have demonstrated that high- supercav…
Electro-optically tunable second-harmonic generation in lithium niobate metasurfaces boosted by Brillouin zone folding induced bound states in the continuum
Huifu Qiu, Xu Tu, Meibao Qin +3
Lithium niobate (LN) metasurfaces exhibit remarkable Pockels effect-driven electro-optic tunability, enabling dynamic control of optical responses through external electric fields.…
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…
