Combining Twisted Light and Plasmons Could Supercharge Data Storage
Research that started out with the humble aim of growing an atomically flat, single crystalline gold surface, ultimately morphed into a team of German and Israeli scientists using the gold surface they came up with for a novel form of data storage.
In research published in the journal Science, a team of scientists from Technion-Israel Institute of Technology and the German universities of Stuttgart, Duisburg-Essen, and Kaiserslautern and the University of Dublin in Ireland has developed a way to exploit the orbital angular momentum of light in a confined device using plasmonics.
Prior to this work, some scientists suggested using the orbital angular momentum of photons as a means for data storage in the open air or in optical fibers. This latest research makes it possible to envision it being used in confined, chip-scale devices.
