Abstract: We consider the propagation of intensity signals in the discrete nonlinear driven-dissipative Schrodinger equation, well-known for the description of a variety of systems from coupled arrays of Kerr nonlinear cavities to exciton-polariton arrays. By periodic switching of a driving laser field, we find that the propagation can be engineered to be unidirectional, while the signals fully withstand dissipation and are resilient against disorder. We anticipate that such a mechanism would be relevant for use in photonic circuits.
