Pre-distorted modal-modulation has been used to carry over 200 channels through a 1km multi-mode fibre in the face of modal and polarisation cross-talk. In the demonstration, by the US University of Rochester, the fibre was constantly measured by a probe beam passing down the fibre in the opposite direction to the would-be data-carrying beam. At the ...

Graphene transistors have been used to create a physically unclonable function (a PUF) – one of the key building blocks of high-end on-chip security. PUFs create numbers from the fine-grained randomness found in in an individual IC, due to doping and manufacturing variations, for example. In this case, variations in the carrier transport of graphene ...
