Abstract
We propose an innovative solution to break reciprocity and obtain one-way subwavelength light propagation. We theoretically demonstrate that the biasing of a graphene sheet by an electric drift current leads to the emergence of one-way surface plasmons. Our findings open interesting perspectives in nonreciprocal photonics and offer new opportunities to control the flow of light at the nanoscale.
