Researchers 3D-printed a low-cost and efficient device that generates twisting light beams with orbital angular momentum and features integrated gain-filtering. WASHINGTON — Researchers have developed ...
Optical vortex beams, characterized by their helical phase fronts and orbital angular momentum (OAM), are pivotal in applications such as high-capacity communication, optical manipulation, and quantum ...
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 ...
