Federated Hierarchical Clustering with Automatic Selection of Optimal Cluster Numbers
Yue Zhang, Chuanlong Qiu, Xinfa Liao +1
Federated Clustering (FC) is an emerging and promising solution in exploring data distribution patterns from distributed and privacy-protected data in an unsupervised manner. Exist…
Non-Abelian interference of topological edge states
Shi Hu, Meiqing Hu, Zhoutao Lei
Topological boundary states exhibit distinctive properties, including unidirectional propagation and noise robustness, which hold significant potential for advancing the performanc…
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.…
Tunable beam splitting via photorefractive nonlinearity and its applications in chiral waveguide induction and vortex generation
Hechong Chen, Zihan Liu, Shengdi Lian +6
We report experimental observation and theoretical explanation of novel propagation regimes for optical beams in an artificial nonlinear material with outstanding photorefractive p…
