Abstract

The criteria and conditions that give rise to the generation of optical frequency comb based on multi-signal interferences in a semiconductor optical amplifier placed in a fiber loop circuit are presented. The study includes effects of the amplifier's material parameters, electrical biasing, and gain profile in the comb frequency generation. A practical optical frequency comb generator was implemented in accordance with the theoretical model developed. The experiment produced a comb frequency spanning 4THz with a spacing of 250GHz in the 1550nm to the 1560 nm band. These experimental results were found to be in good agreement with theoretical predictions.
