ResumenGraphene has attracted recently a great deal of attention due to its amazing electronic properties. Remarkably, even one-atom-thick graphene can bind electromagnetic modes (surface plasmon polaritons), despite being almost transparent. This brings to the fore the possibility of using graphene for many of the functionalities sought within the field of plasmonics, with the advantage that graphene the carrier concentration in graphene can be modulated by external gates. In the first part of this talk we will analyze the spacial distribution of the electromagnetic field radiated by a nanoemitter in graphene, as a function of frequency and doping concentration. We will show the appearance of different regimes in the field dependence on distance to the source. In the second part, we will use this information to analyze the superradiance of two emitters mediated by graphene surface plasmons.
