The control of rogue wave in the mid-infrared supercontinuum with seed time delay

The control of rogue waves in mid-infrared SC generated by pumped femtosecond pulses in chalcogenic optical fibers abnormal dispersion has been studied. And the control effect of the time delay between the seed light and the pump light on the rogue wave in the mid infrared supercontinuum is numerically studied. A seed is emitted into the photonic crystal fiber with an appropriate time delay to control the soliton trajectory. The results show that the appropriate negative time delay will increase the possibility of the formation of rogue waves in the mid-infrared supercontinuum, while the appropriate positive time delay will inhibit the formation of rogue waves. In addition, we also numerically study the influence of the peak power of the pump light on the formation of rogue waves. With the change of peak power, rogue waves will be promoted or suppressed. We believe that this study will provide new insights into the control of rogue waves.
