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 ...

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 ...

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.

Researchers have developed a 3D-printed device that generates twisting light beams with orbital angular momentum (OAM), a form of rotational energy that can carry more data than regular beams.

Researchers from Jinan University, under the direction of Professor Yanjun Bao and Baojun Li, developed a novel metasurface-based imaging method that allows for the simultaneous measurement of ...

Researchers have developed a single metasurface that can effectively tune the different properties of laser light, including wavelength, without the need of additional optical components. The ...

(Nanowerk News) Reconfigurable metasurfaces are transforming wireless communication by adjusting electromagnetic (EM) wave characteristics such as amplitude, phase, and polarization. These planar ...
