But although optical fibers are increasingly replacing copper wires, carrying information via photons instead of electrons, today's computer technology still relies on electronic chips.

Researchers at the National University of Singapore have invented a graphene-based polarizer that can broaden the bandwidth of prevailing optical fiber-based telecommunication systems.
