Abstract
Methods, systems, and apparatus for phase-sensitive regeneration of a signal without a phase-locked loop and using Brillouin amplification. The system for phase-sensitive regeneration includes a data channel, one or more pumps and a mixing stage. The one or more pumps are coupled with the data channel. The mixing stage is coupled with the data channel and is for processing a data signal that is combined with an output of the one or more pumps and idler or higher harmonic. The mixing stage is configured to amplify the idler or higher harmonic using Brillouin amplification in a Brillouin gain medium to keep the one or more pumps and the data channel phase-locked.
