One-dimensional light on graphene

Nanostructured graphene illuminated with light holds potential for a wide range of applications in photonics and optoelectronics, including infrared and terahertz photodetectors, sensors, reflect arrays or modulators. Development of graphene nanopatterning technology has in recent years enabled the construction of such devices that hold promise for a quick transfer from scientific labs to the marketplace. Now scientists have carefully mapped, with nanoresolution, the structure of light on graphene nanoresonators, observing light that is confined to extremely small volumes at the edges of the nanostructures. The nearly 1D form of this light is expected to lead to novel device applications, for example to efficient control of quantum emitters, a sort of “bit” in future quantum computers.
