Hybrid integration of silicon waveguides with nonlinear organic materials is a way to enhance nonlinear optical properties of silicon-on-insulator nanophotonic devices. Highly nonlinear slot waveguides have been fabricated using deep-UV lithography, standard CMOS processing, and organic molecular beam deposition of a small molecule with a high third-order optical polarizability. The waveguides feature ultrafast Kerr-nonlinearities with nonlinear parameters of 104000 1/[W km] and without measurable impairment by two photon induced free carriers. Amplitude and phase dynamics of these waveguides have been characterized using a heterodyne pump-probe technique.
