Electronic fibre in graphene

We investigate theoretically the transmission properties through a p-n-p junction on graphene. Here we show that the electronic transport property presents deep analogies with light propagation. It originates from the similarity between the linear spectrum of the Dirac fermions and photons that obey the Maxwell's equations. We demonstrate the p-n-p channel acts as a electronic fiber in which electrons propagate along the channel without dissipation.
