【 摘 要 】

Electro-optical response of a current-carrying monolayer graphene is studied theoretically. Our calculation takes into account full (diagonal and nondiagonal) 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 midinfrared frequency range.
