title: Active control and stability in microring resonator chains.
abstract: In this paper, we study analytically and numerically the light propagation in microring resonator chains that exhibit distributed loss or gain. We derive the stability conditions for the latter and demonstrate the feasibility of the group index control within a certain amplification range. Possible applications of the discussed effects are proposed.
