Graphene, a two-dimensional material made up of a single layer of carbon atoms, has long been known for its strength and electrical capabilities. Now, researchers from the University of Manchester have made a new discovery that could revolutionize the use of graphene in many applications.

In a new study published in Nature Nanotechnology, the researchers have demonstrated that graphene can be made to absorb light at an intensity and scale never seen before. This breakthrough could potentially lead to the development of new graphene-based applications that are more efficient and powerful, such as ultrafast optical communication devices.

The team achieved this by using a technique called “plasmonic nanostructuring” to create an array of tiny nano-antennas on the surface of graphene. This allowed them to focus light on a single graphene sheet and absorb it at an intensity up to 40,000 times higher than previously possible.

The breakthrough could have significant implications for a variety of fields, particularly in the development of optical communication devices. The team’s findings suggest that graphene-based optical devices could be more efficient and powerful than existing technologies, potentially leading to faster and cheaper communication solutions.
