A method for the optimization of χ(2) coupling phenomena in slab waveguides on the basis of reduced parameters is presented. It is shown that the configuration for maximum second harmonic generation (SHG) efficiency is given by a single chart with two normalized parameters only. This optimization procedure is illustrated for the case of SHG in the nonlinear cladding of a linear step index waveguide.
