Optical Angular Momentum Shatters Data Ceiling
BERKELEY, Calif., March 1, 2021 — An optical antenna developed by researchers at the University of California, Berkeley, can, in principle, provide limitless bandwidth. The technology takes advantage of orbital angular momentum (OAM), a characteristic of light that enables multiplexing, or simultaneous transmission, exponentially greater than current technology. According to Boubacar Kanté, the study’s principal investigator and the Chenming Hu Associate Professor at UC Berkeley’s Department of
