100-GHz step-tunable single-frequency erbium-doped fiber lasers

摘要

Abstract: Novel step-tunable single-frequency fiber lasers in ring or linear configurations are presented. The frequency discriminating elements are periodic filters, either sampled fiber Bragg gratings or Fabry-Perot micro-etalons. The lasers can be step-tuned to exact multiples of 100 GHz and they find applications in frequency referencing for DWDM communication systems. !24
