Electro-Optics of Current-carrying Graphene
Abstract
Electro-optical response of a current-carrying monolayer graphene is studied theoretically. Our calculation takes into account full (diagonal and non-diagonal) conductivity tensor obtained from a particle-conserving out-of-equilibrium distribution function of doped graphene. Our analytical and numerical results indicate that the presence of a moderate DC current throughout a doped graphene channel induces large Kerr rotations within a frequency range which can be tuned up to the mid-infrared frequency range.
