Researchers in Singapore have invented a graphene-based polarizer that can broaden the bandwidth of prevailing optical fiber-based telecommunication systems. The research team invented an ultra-slim broadband polarizer that uses graphene, a single-atomic-layer crystallized carbon, to convert light beam into polarized light. This is the first experimental demonstration of using graphene as an ultrathin waveguide to couple and modulate light.
