Abstract :
A strongly coupled multiple-quantum-well (MQW)-sandwich nonlinear directional coupler is analyzed using the Galerkin finite-element method (FEM) accompanied with a predictor-corrector algorithm. The error in power conservation is very small and does not accumulate with propagation, unlike the beam propagation method. The coupler is found to have the advantages of relatively low switching power and short coupling length.<>
