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 ...

Optical vortex plays an important role in a variety of fields, such as particle tweezing, quantum communication, astrophysics, and microscopy. Especially, the application of optical vortex has been ...

In the 1600s, Kepler proposed that the momentum of sunlight was the reason that the visible tails of comets pointed away from the sun. Beyond this optical linear momentum, in the early 1900s, Poynting ...

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 ...

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

Pushing the limits of structured light, physicists report a new type of optical vortex beam that not only twists as it travels but also changes in different parts at different rates to create unique ...

Photons can have half-integer values of angular momentum when they are confined to fewer than three dimensions. That is the conclusion of physicists in Ireland, who have revived an experiment first ...

The late 20th and early 21st century have seen a revolution in the study of light. Far from the old days of seeing things dimly through microscopes, we are now in the position to freeze light, use it ...
