Precise dark pulse synthesis and its nonlinear applications

在本研究中，我们利用频域逐行强度和相位调制产生暗脉冲，特别是暗孤子。研究了它们的光纤传输特性和非线性光学特性，提出了一种利用光脉冲合成器精确合成暗脉冲的方法。我们通过正常色散光纤传输了暗孤子，并从实验上证实了其孤子传输功率与理论相符。在高功率区，由于高阶孤立子压缩，脉冲被压缩并光谱展宽。

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.
