(MENAFN- EIN Presswire) EINPresswire/ -- Vortex phenomena are widespread in nature, from typhoons to ocean currents. In the field of optics, vortex beams, which carry orbital angular momentum, have ...

The quest for a real life tractor beam continues, with a 2-micrometer-thick silicon light bender. The silicon metasurface changes a solid beam into a triple spiral one that can pick up particles.

A single geometric metasurface is used to form SC-PVVB with multidimensional modulation ability for optical encryption, enabling precise control over the beam's morphology, polarization azimuth and ...

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 ...
