| Graphene can polarize light: Researchers demonstrate world's thinnest polarizer Posted: 30 May 2011 07:52 AM PDT Graphene, an ultra-flat monolayer of carbon atoms in a hexagonal crystal lattice, has attracted a strong wave of research interest due to its unique electrical and photonic properties. Now, researchers have demonstrated the world's thinnest polarizer, which relies on the coupling, guiding and polarizing of electromagnetic waves by graphene. They claim that this breakthrough will someday allow the integration on all-photonic circuits for high-speed optical communications.  |
