Researchers at the Institute for Basic Science (IBS) in Korea, in cooperation with KAIST, have announced the development of a graphene-based metamaterial device that can control the speed of light.
The team explains that light is the most useful means for data transmission, but it should be converted into electrical signals in order to do that. In this process, the speed of light is slowed down due to the limitations of electronic signal processors.
By combining graphene with a metamaterial, the researchers have developed a device that can slow down the speed of light and then accelerate it. The new device is expected to help develop next-generation optical communication devices.
