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 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.

(Nanowerk News) Metasurface technology is an advanced optical technology that is thinner, lighter, and capable of precisely controlling light through nanometer-sized artificial structures compared to ...

In the dynamic realm of optical physics, researchers are continually pushing the boundaries of how light can be manipulated and harnessed for practical applications. As reported in Advanced Photonics ...

Directly reconstructing the physical wavefront of objects in target scene for watched naturally by human eyes, holographic display is considered as one of ultimate display technology. Spatial light ...
