We present several approaches for orders-of-magnitude enhancement of optical nonlinearities in specially engineered nanostructures containing graphene and other 2D materials and illustrate how they apply to second- and third-harmonic generation in such 2D-3D photonic heteromaterials. Applications to active photonic devices, such as nonlinear optical gratings, are discussed as well.
