| Research Abstract |
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.
