This calculated diffraction image shows how forked diffraction gratings shape the atoms' wave function into a vortex. (Courtesy: Science/AAAS) A wave-like property previously only seen in beams of ...

Propagate light through any kind of medium – be it free space or biological tissue – and light will scatter. Robustness to scattering is a common requirement for communications and for imaging systems ...

The proposed vortex beam can carry vast amounts of information, making them ideal for dense data communication systems. Scientists have developed a breakthrough optical technology that could ...

To study nanoscale patterns in tiny electronic or photonic components, a new method based on lensless imaging allows for near-perfect high-resolution microscopy. This is especially important at ...

Optical vortices, characterized by a helical phase front and doughnut-shaped intensity distribution, contribute to a broad range of applications, from microscopy to optical communications. And ...

The Fourth Industrial Revolution is driving exponential growth in data transmission, and cost-effective, ultrafast, and compact optical communication technologies are urgently needed to manage the ...

Physicists have created the first-ever atomic vortex beam — a swirling tornado of atoms and molecules with mysterious properties that have yet to be understood. By sending a straight beam of helium ...

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 ...
