| Outline of Final Research Achievements |
In the future transparent optical networks, wavelength conversion or multicast (WCM) plays an important role to enhance the flexibility of wavelength management and the non-blocking capacity. On the other hand, to meet the increasing bandwidth demands, high-order formats have been proposed and widely deployed in optical networks. Therefore, it is crucial to exploit WCM schemes with tolerance against phase noise, especially for phase-noise-sensitive high-order formats. We proposed coherent pumping in WCM to cancel the phase noise from pumps, which is suitable for high-order formats. We have successfully verified the feasibility of our scheme and experimentally demonstrated pump-phase-noise-free wavelength conversion, multicast and data exchange for high-order formats using coherent pumps. The results have been published in top-tier conference and journals in the field.
