The proposed vortex beam can carry vast amounts of information ... Researchers used a specially designed Dammann grating to generate arrays of SC-PVVBs, maximizing their data-carrying potential.

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 ...

But vortex beams’ waves don’t slosh up and down like ripples on water. Instead, the beams’ particles have wave functions that move in a corkscrewing motion as a beam travels through space.

Finally, the signals are transmitted through a circular array of antennas to produce a vortex beam with the desired properties. Fabrication and testing After performing advanced simulations to ...

Researchers utilize the polarization singularity located at the at-Γ bound state in the continuum in the momentum space to generate the vortex beam. Since the singularity exists in the momentum ...

The researchers also introduced a spiral phase plate to the 1,553-nm beam before frequency mixing, resulting in the generation of a vortex beam carrying orbital angular momentum. This marks the ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars ...

Canberra physicists have developed a 'vortex beam' capable of carrying a tiny bead of glass 1.5 metres along its axis. Using a five-watt laser, the team generated a hollow, donut-shaped beam and ...

Researchers have managed to create a “twisted” beam that can transmit 2.56 terabits of data per second wirelessly. Researchers have managed to create a “twisted” beam that can transmit 2. ...
