Abstract

We analyse the effects of gain and loss on the group velocity of light propagating in microring resonator chains. These are shown to permit the nonlinear all-optical control of the transmission delay in ring resonator microstructures. In the superluminal regime, the analysis of lossy structures provides a general framework for the description of faster-than-light optical signal transmission of narrowband pulses at resonances in dissipative media.
