“…First, an SOI waveguide with rib width 1800 nm, slab height 100 nm, SOI height 220 nm, propagation length 2 cm and one dip of width 400 nm and depth 70 nm is considered. Figure 2 shows the waveguide's geometry, which is the same as in Kernetzky et al (2020). Table 2 summarizes the input/output wavelengths and their corresponding modes, optimized for best efficiency of the OPC process.…”

“…For achieving a strong idler build-up, phase matching (PM) has to be performed and multi-mode operation is usually preferred since an additional degree of freedom is obtained. We refer to Kernetzky et al (2020) for a detailed analysis of geometry optimization for PM in SOI waveguides. In Höfler et al (2021) we described a model for the susceptibility calculation in silicon.…”

We derive propagation equations modeling third-order susceptibility-induced nonlinear interaction and linear mode coupling in waveguides. We model material susceptibility with Raman and electronic response which include approximations suited for optical communications. We validate our model by comparing numerical integration of the propagation equations to continuous wave measurements of a silicon on insulator waveguide.
