Optical hopfions with arbitrary two winding numbers
Xinji Zeng, Jinwen Wang, Yun Chen +10
Hopfions, as three-dimensional topologically nontrivial structures described by poloidal and toroidal winding numbers, hold promise as robust information carriers in spintronics, f…

Generation and characterization of customized perfect Laguerre-Gaussian beams with arbitrary profiles
Chengyuan Wang, Yun Chen, Jinwen Wang +3
We experimentally demonstrate the generation of customized perfect Laguerre-Gaussian (PLG) beams whose intensity maxima localized around any desired curves. The principle is to act…
