Paper Abstract

Two semiconductor optical amplifiers (SOAs) are directly coupled by connecting the output of each to the input of the other. This provides positive feedback for an inverted optical threshold; there is negligible output above a specified threshold. The SOA pair is analyzed and simulated to optimize parameters. Two SOA pairs are cross-connected in a similar manner by connecting the output of each pair to the input of the other, to construct an R-S flip-flop. Analysis shows that only two states exist. Simulation is used to demonstrate setting and resetting the R-S flip-flop at up to 5 Gbps.
