The Akhmediev breather formalism of modulation instability is extended to describe the spectral dynamics of induced multiple sideband generation from a modulated continuous wave field. Exact theoretical results describing the frequency domain evolution are compared with experiments performed using single mode fiber around 1550 nm. The spectral theory is shown to reproduce the depletion dynamics of an injected modulated continuous wave pump and to describe the Fermi-Pasta-Ulam recurrence and recovery towards the initial state. Realistic simulations including higher-order dispersion, loss, and Raman scattering are used to identify that the primary physical factors that preclude perfect recurrence are related to imperfect initial conditions.
将阿赫麦德耶夫呼吸子调制不稳定性形式扩展到描述从调制连续波场中产生的诱导多边带产生的光谱动力学。描述频域演化的精确理论结果与在 1550nm 左右使用单模光纤进行的实验进行了比较。该光谱理论再现了注入调制连续波泵的耗散动力学，并描述了费米-帕斯塔-乌伦（Fermi-Pasta-Ulam）的恢复和恢复到初始状态。包括高阶色散、损耗和拉曼散射的实际模拟用于确定阻止完美恢复的主要物理因素与不完美的初始条件有关。
