Scaling rules for slab waveguides with nonlinear substrate.
A mode power measure is introduced to characterize optical slab waveguides with nonlinear substrate or cover. Together with the normalized film thickness and asymmetry coefficient, it allows for determining guiding properties in a way analogous to the description of Kogelnik and Ramaswamy for the linear waveguides and permits an easy interpretation and design of nonlinear slab waveguides. The universal dispersion curves for the TE modes are presented.
