Graphene could enable better high-speed, long distance transmission performance than silicon-based fiber optics, the best structures currently in use. 

University of Wisconsin–Madison researchers fabricated graphene into 12-nanometer ribbon structures using a method that makes scaling-up simple. Tests with the nanoribbons had the scientists closing in on the properties needed to move graphene toward usefulness in telecommunications equipment.

The researchers describe their work in "Using Bottom-Up Lithography and Optical Nonlocality to Create Short-Wave Infrared Plasmonic Resonances in Graphene," published in ACS Photonics.

"In our study, we created a scalable fabrication technique to make the smallest graphene ribbon structures yet and found that with modest further reductions in ribbon width, we can start getting to telecommunications range," says Joel Siegel, a UW–Madison graduate student and co-lead author of the study.
