Photonic applications of graphene

Graphene can be used to enhance photonics, as a detector for light, an optoelectronic transceiver, or as part of high-resolution imaging systems. A surprising application of graphene is its use in photodetectors. Light detection capabilities of graphene are inherently limited because a single sheet of the material absorbs only ~2.3%...

Graphene optical communications gain speed

Optical communication formed the backbone of the internet age and is expected to be equally pivotal for the developing 5G networks. Modern communications rely on optical links that fly information at the speed of light, and on circuitry such as photodetectors and modulators which is able to encode a wealth...
