We report phase and amplitude measurements of large coherent structures originating from the noise-induced modulation instability in optical fibers. By using a specifically designed time-lens system (SEAHORSE) in which aberrations are compensated, the complex field is recorded in single-shot over long durations of 200 ps with sub-picosecond resolution. Signatures of Akhmediev breather-like patterns are identified in the ultrafast temporal dynamics in very good agreement with numerical predictions based on the nonlinear Schrödinger equation.

利用外差时间成像技术，单次观察呼吸噪声引起的调制不稳定性

我们报告了大相干结构的相位和幅度测量结果，这些相干结构源自光纤中由噪声引起的调制不稳定性。通过使用经过特别设计的时差系统（SEAHORSE），在该系统中可以补偿像差，可以在200 ps的长时间内以单皮秒的分辨率记录复杂的场。在超快速的时间动态中，与基于非线性Schrödinger方程的数值预测非常吻合，识别出了类似Akhmediev呼吸模式的特征。
