Precise dark pulse synthesis and its nonlinear applications

在本研究中，我们通过频域逐行强度和相位调制来产生暗脉冲，特别是暗孤子。研究了它们的光纤传输和光非线性特性。我们开发了一种利用光脉冲合成器精确合成暗脉冲的技术。我们通过普通色散光纤传输暗孤子，实验证实了它们的孤子传输功率与理论相符。在高功率状态下，由于高阶孤子压缩，脉冲被压缩，频谱被展宽。

In this study, we generated dark pulses, especially dark solitons, by line-by-line intensity and phase modulation in frequency domain. We investigated their fiber transmission and optical nonlinear characteristics.We developed a technique to precisely synthesize dark pulses using an optical pulse synthesizer. We transmitted the dark solitons through a normal dispersion fiber and experimentally confirmed that their soliton transmission power matched with the theory. In the high power regime, the pulse was compressed and spectrally broadened due to the higher order soliton compression.
