One important form is called an optical vortex beam. Unlike an ordinary light beam with a flat wavefront, an optical vortex beam has a twisted, corkscrew-like phase structure and a dark center, much ...
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 ...
A new research study from Opto-Electronic Advances discusses tailoring electron vortex beams with customizable intensity patterns by electron diffraction holography. In recent years, the scientific ...
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 ...
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 ...
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 ...
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 ...
Scientists have developed a breakthrough optical technology that could dramatically enhance the capacity and security of data transmission (Fig. 1). By utilizing a new type of spatial-frequency ...
