Abstract :
The effective index method is very useful for studies of waveguides with index variations in both directions perpendicular to the direction of propagation, e.g., semiconductor lasers. In this paper we investigate the case of nonplanar layers and simultaneous presence of an index perturbation. The accuracy of the first order expression is investigated and formulas for the higher order terms are given.
