Linear and nonlinear optical tuning with SbS-based metasurfaces
Amin Zamani, Meibao Qin, Gabriel Sanderson +11
Here, we experimentally demonstrate the unique properties of SbS metasurfaces on monolithic and hybridised SbS-Si platforms. Their advantages are particularly prono…
Doubly resonant nonlinear metasurfaces enabling NIR-to-UV upconversion for reconfigurable Fourier optical processing
Jumin Qiu, Meibao Qin, Tingting Liu +6
Fourier optical processing underpins optical information manipulation, yet extending such operations to short wavelengths within compact platforms remains challenging. Here, we add…
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…
Developing a ChatGPT-Based Tool for Physics Experiment Teaching
Yifeng Liu, Min Li, Zhaojun Zhang +2
This paper examines how advanced AI assistants can help physics educators create practical teaching tools without specialized programming skills. Using the square-wave synthesis ex…
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.…
