GarcĂ­a de Abajo A1 - M. D. Lukin AB - We show that it is possible to realize significant nonlinear optical interactions at the few photon level in graphene nanostructures. Our approach takes advantage of the electric field enhancement associated with the strong confinement of graphene plasmons and the large intrinsic nonlinearity of graphene. Such a system could provide a powerful platform for quantum nonlinear optical control of light. As an example, we consider an integrated optical device that exploits this large nonlinearity to realize a single photon switch. VL - 111 UR - http://arxiv.org/abs/1309.2651v3 CP - 24 J1 - Phys. Rev.
