Optical vortex beams, characterized by their helical phase fronts and orbital angular momentum (OAM), are pivotal in applications such as high-capacity communication, optical manipulation, and quantum ...

A research team led by Associate Prof. Wang Anting from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) proposed a method for multidimensional ...

Imagine a whirlpool spinning in a river, or a tornado swirling through the sky. They don't just spin on the spot: they travel forward while maintaining that spiraling motion inside them. These ...

Recent advances in femtosecond optical vortices (FOVs)—characterized by helical wavefronts and high peak power—have enabled breakthroughs in attosecond vortex generation and 3D chiral microfabrication ...
