Abstract


  • We demonstrate that within the model of massless Dirac fermions, graphene has a strong nonlinear

    optical response in the terahertz regime. It is found that the nonlinear contribution significantly

    alters both the single frequency and frequency tripled optical response at experimentally relevant

    field strengths. The optical activity of single layer graphene is significantly enhanced by nonlinear

    effects, and the frequency tripled response opens the gateway to photonic and optoelectronic device

    applications.
