Abstract :
We investigate refractive-index engineering in form-birefringent AlGaAs-AlAs multilayer waveguides aiming at the maximization of the phase-matching bandwidth for difference frequency generation. Acting on layer thickness and sequence, we predict a threefold improvement, as compared to previously reported results
