US researchers say they have built a laser system precise and powerful enough to control vast grids of atoms, a step they ...
The terahertz (THz) band of the electromagnetic spectrum holds immense promise for next-generation technologies, including high-speed wireless communication, advanced encryption, and medical imaging.
Columbia researchers Sebastian Will and Nanfang Yu combine optical tweezers with metasurfaces to trap over 1,000 atoms—with the potential to capture hundreds of thousands more.
5G-Advanced and 6G wireless communication technologies aim to achieve the interconnection of all things. This encompasses not only traditional base stations and mobile devices but also diverse sensors ...
(Nanowerk Spotlight) Light carries information in its wavelength, wavevector direction, polarization, and the way it bends through materials. Until now, optical data storage has typically used just ...
