Abstract :
We address the potential of a coupled plasmonic waveguides system with gain 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. The positive role of losses allowing to lower the total amount of gain required for switching is particularly emphasized.
