We present a theoretical model to study the nonlinear optical response of materials with a low-energy spectrum characterized by strongly tilted, type-II Weyl cones in two dimensions, which we call 2D Weyl materials. Our findings reveal that the tilted nature of the Weyl cones is responsible for the appearance of even harmonics in the nonlinear signal, as well as its strong polarization dependence. We discuss how it is possible to control such a nonlinear response and envision how 2D Weyl materials can be used to realize different photonic devices for sensing applications.
