A new publication from Opto-Electronic Advances, 10.29026/oes.2024.240001 discusses robust detection technology of orbital angular momentum of partially coherent vortex light fields in complex ...

The vortex is ubiquitous in nature, spanning from the galaxy, ocean flow, to phyllotaxis. In electromagnetic wave, the vortex can be found in spiral wavefront profiles, representing the orbital ...

(Nanowerk News) A new publication from Opto-Electronic Advances ("Tailoring electron vortex beams with customizable intensity patterns by electron diffraction holography"), discusses tailoring ...

The larger the orbital angular momentum, the longer the vortex takes to spin around. Interestingly, the observation of the vortex dynamics can also be used to distinguish the helicity of the light, ...

(Nanowerk News) Plasmonic vortex is an optical field distribution with topological features formed by interfering surface plasmons, which enriches the class of vortex phenomena in nature. Owing to ...

To break through a looming bandwidth bottleneck, engineers are exploring some of light's harder-to-control properties. Now, two new studies have shown a system that can manipulate and detect one such ...

Like soft serve ice cream, beams of atoms and molecules now come with a swirl. Vortex beams made of light or electrons have shown promise for making special types of microscope images and for ...

There’s a new kind of twisted light. A rotating “vortex beam” whose twist changes across the length of the beam has been created in the lab for the first time. Researchers discovered in 1992 that a ...
