Although forbidden in the electric-dipole approximation, the second-order susceptibility is surprisingly high, equivalent to the bulk magnitude above $10^{-3}$ m/V. We consider the graphene monolayer as a nonlinear optical component of a monolithic photonic chip with integrated pump fields. The nonlinear power conversion efficiency of the order of tens $\\mu$W/W$^2$ is predicted from structures of $10-100$ $\\mu$m size. We","authors_text":"Alexey Belyanin, A.
