The χ(3) nonlinear properties of slotted hybrid silicon photonic waveguides infiltered with third-order nonlinear materials (NM) are studied by calculating the effective nonlinear susceptibilities associated to the silicon and cladding material, respectively. Optimization of the geometry of silicon-slotted waveguides is performed to engineer the nonlinear figure of merit (FOMTPA) of the guided mode up to 4.25, which is related to the balance between the Kerr and the TPA effects. The importance of engineering the nonlinear FOMTPA is illustrated by simulating the self-phase modulation effect in slotted hybrid silicon photonic waveguides.
