The authors report on a systematic procedure for optimizing the second order susceptibility in semiconductor quantum wells (QWs) based on ternary alloys. The procedure relies on combining the supersymmetric and the coordinate transform methods. Optimized design of AlxGa1−xAs based QWs gives nonlinearity somewhat larger than is presently achieved in this system.
