Researchers from the National University of Singapore (NUS) invented a graphene-based an ultra-slim broadband polarizer. They say that such a polarizer can broaden the bandwidth of fiber optic networks. A graphene polarizer covers the telecommunication bands from visible to mid-infrared which means that it can be a complete solution for multiple-channel communications.

The team says that unlike regular polarizers (made from thin metal film or semiconductor dielectric) a graphene polarizer has the unique ability to filter out transverse-magnetic-mode and supports transverse-electric-mode surface wave propagation.
