Spintronics Technology Revolution Could Be Just a Hopfion Away A decade ago, the discovery of quasiparticles called magnetic skyrmions provided important new clues into how microscopic spin textures will enable spintronics, a new class of electronics that use the orientation of an electron’s spin rather than its charge to encode data.  But although scientists have made big advances in this very young field, they still don’t fully understand how to design spintronics materials that would allow for ultrasmall, ultrafast, l...

Light Unbound: Data Limits Could Vanish with New Optical Antennas Researchers at the University of California, Berkeley, have found a new way to harness properties of light waves that can radically increase the amount of data they carry. They demonstrated the emission of discrete twisting laser beams from antennas made up of concentric rings roughly equal to the diameter of a human hair, small enough to be placed on computer chips. The new work, reported in a paper published Feb. 25 in the journal Nature Physics, throws wide ...

On-chip optical antennas remove data limits March 02, 2021 // By Jean-Pierre Joosting Latest research throws wide open the amount of data or information that can be simultaneously transmitted by a single light source. A new method of harnessing the properties of light waves that can radically increase the amount of data they carry has been discovered by researchers at the University of California, Berkeley. They demonstrated the emission of discrete twisting laser beams from antennas made up of concentric rings roughly equal to the diameter of a human hair, small eno...
