Collaborative Research: Mathematical and Engineering Study of Multi-Channel All-Optical Regenerator

本文提出了一种设计和实现多通道全光再生器的方案。阳离子和整形）能力。提出的再生器是一种新的设备，有可能扩大的范围，并降低基于光纤的光传输系统的成本。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，拟议的设备需要一个复杂的研究，在一个强脉冲的演变？具有周期性色散补偿的BER。这个问题不同于色散管理传输系统中的脉冲传播，因为在后一种情况下，传播只是弱非线性的。我们希望这个项目的数学部分的结果将是一个理论，将描述在上述条件下的脉冲传播和扰动对这种传播的影响。目前还没有这样的理论存在。所提出的再生器可以潜在地用于任何数量的信道，并且不需要它们的时间同步或任何极化控制。co-PI最近已经在数值上证明了这种2 R再生器的可行性，据他们所知，这是在上述条件下首次证明多通道全光再生。

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.
