【 摘 要 】

We numerically simulate the effects of the wavelength difference between the pump light and the seed light on the mid infrared supercontinuum and rogue wave under the condition of fiber group velocity matching. The results show that with the increase of the wavelength difference between the two pulses, the filling effect of the spectrum and the control of rogue wave first increase and then decrease. The appropriate wavelength difference can realize the effective control of rogue wave. In addition, the modulation depth and pulse width of seed light play an important role in the control of rogue wave. The control effect of rogue wave first increases and then decreases with the increase of modulation depth and pulse width.
