We address the potential of a nonuniform coupled waveguides system with gain and loss featuring a PT-symmetry configuration for the realization of switching and dynamic memory applications based on a non-reciprocal modal behavior. The possibility for a perfect switching operation in such a nonconservative layout combining loss and gain is demonstrated.
