2R regenerator based on high non-linear dispersion-imbalanced loop mirror

A 2R regenerator is demonstrated for the first time based on high non-linear dispersion-imbalanced loop mirror (HN-DILM). Theoretical results show that the increment of the extinction ratio and Q-factor could be achieved by using the HN-DILM when carefully choosing the input peak power. The receiver sensitivity of a noise-loaded 10 Gbit/s signal is improved by 2.9 dB by using the 2R regenerator.
