This is a proposal to design and build a multi-channel all-optical regenerator with a 2R (reampli?cation and reshaping) capability. The proposed regenerator is a novel device that has the potential to extend the reach and reduce the cost of fiber based optical transmission systems. The proposal covers both the mathematical design, optimization, simulation and the initial experimental testing of the planned system. Mathematically, the proposed device requires a complex study of the evolution of an intense pulse in a ?ber with periodic dispersion compensation. This problem is different from that of pulse propagation in dispersion-managed transmission systems, because in the latter case, the propagation is only weakly nonlinear. We expect that the outcome of the mathematical part of this project will be a theory that will describe both the pulse propagation under the conditions described above and the effect of perturbations on this propagation. No such a theory exists at the present time.The proposed regenerator can potentially be used for any number of channels and does not require their temporal synchronization or any polarization control. The co-PIs have recently numerically demonstrated the feasibility of such a 2R regenerator, which, to the best of their knowledge, was the first demonstration of multi-channel all-optical regeneration under the above conditions.

这是一项设计和构建具有 2R（重放大和整形）能力的多通道全光再生器的提案。所提出的再生器是一种新颖的设备，有可能扩大基于光纤的光传输系统的覆盖范围并降低其成本。该提案涵盖了计划系统的数学设计、优化、模拟和初始实验测试。从数学上讲，所提出的装置需要对具有周期性色散补偿的光纤中强脉冲的演化进行复杂的研究。这个问题与色散管理传输系统中的脉冲传播问题不同，因为在后一种情况下，传播只是弱非线性的。我们期望该项目的数学部分的结果将是一个理论，该理论将描述上述条件下的脉冲传播以及扰动对此传播的影响。目前不存在这样的理论。所提出的再生器可以潜在地用于任意数量的信道并且不需要它们的时间同步或任何偏振控制。共同PI最近通过数值证明了这种2R再生器的可行性，据他们所知，这是在上述条件下首次演示多通道全光再生。
