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.
