A group of researchers, led by the University of vienna, have found that by creating structures out of a single layer of graphene can allow for strong optical nonlinearities, and can in turn convert light, according to Graphene Info.

This process is achieved by using gold ribbons the size of a nanometer to squeeze the light into atomically-thin graphene. This discovery could allow for a new set of small, tunable, nonlinear devices.

Irati Alonso Calafell, the lead author of the paper had this to say, “we have shown that the relatively simple gold nanoribbons can simultaneously enhance graphene’s nonlinearity, excite graphene plasmons, and create a plasmonic cavity”.

While this specific field has not yet been properly explored or realized, there is great potential that could help probing new physics in graphene heterostructures, and advancing graphene devices as a whole.
