We derive from Maxwell's equations full-vectorial nonlinear propagation of four-wave mixing valid in straight semiconductor-on-insulator waveguides. Special attention is given to the resulting effective mode area, which takes a convenient form known studies photonic crystal fibers, but has not been introduced context integrated show that difference between our area and scalar equivalent often referred literature may lead mistakes when evaluating refractive index optimizing designs new verify results derivation by comparing it experimental measurements silicon-on-insulator waveguide, taking tolerances on fabrication parameters into account.
