Storage and retrieval of optical skyrmions with topological characteristics
Jinwen Wang, Xin Yang, Yun Chen +10
Optical skyrmions are topological structures of light whose defining property, the skyrmion number, is robust against perturbations. This makes them attractive for applications in…
Super-resolution optical trapping of multiple cold atoms
Kelvin Lim, Vincent Mancois, Haijun Wu +2
Arrays of optical tweezers form the backbone of neutral atoms analog and digital quantum processors. However, the inter-trap distance remains generally much larger than the size of…
Visualized Geometric Phase of Caustic Geometric Beams
Haiyang Li, Yijie Shen
Detecting Pancharatnam-Berry geometric phases of light typically requires interferometry or diffraction through a specially truncated aperture. Here, we introduce a simpler method…
Freespace twistronics for optical supertopologies
Vasu Dev, Yijie Shen
Twistronics, the study of moiré superlattices of twisted bilayer 2D materials creating nontrivial physical effects, has recently revolutionized diverse subjects from materials to…
Tailoring ultra-high-order optical skyrmions
Xinji Zeng, Jing Fang, Haijun Wu +9
Skyrmions, as quasiparticles with topological spin textures, has recently garnered great attention for both condensed matter and structured wave communities, promising next-generat…
Fully Tunable On-Chip Meta-Generator for Multidimensional Poincaré Sphere mapping
Jing Luan, Tiange Wu, Shuang Zheng +7
The angular momentum of light can be elegantly mapped onto high-order Poincare spheres, providing a powerful framework for describing structured light beams. Such beams have shown…
