In this paper we theoretically study the nonlinear dynamics of Wannier-Starkstates in the dissipative system consisting of interacting optical resonators,whose resonant frequencies depend linearly on their number. It is shown thatthe negative losses in some resonators can switch the system into a lasingregime with Wannier-Stark states serving as working modes. It is shown byextensive numerical simulations that there may be single-frequency stationaryregimes as well as multi-frequency regimes. In the latter case Blochoscillations can appear in the system. The possibility of selective excitationof Wannier-Stark states by the appropriate choice of the dissipation profile isinvestigated. A simple perturbation theory describing the quasi-linear regimesis developed and compared against the numerical results.
