New Graphene Film Brings Fast, Low-Cost Communications

A team from Swinburne University of Technology has developed the micrometer-thin continuous graphene oxide film, which demonstrates optical nonlinearity suitable for high-performance integrated photonic devices used in communications, biomedicine and computing.

Researchers created the thin film by spinning a coated graphene oxide solution onto a glass surface. Through a laser-induced reduction process, they created microstructures on the graphene oxide film, which allowed them to tune the nonlinearity of the material.
