摘要
In the paper, the modulation instability (MI) of the pulses with different powers is studied based on the modified coupled nonlinear Schrodinger equations in nonlinear fiber. By analyzing MI gain spectrum with different power ratios, it shows that the increase of power ratio leads to the diminution in the range of strongly unstable frequency and the decrease in the gain of MI spectra. With a fixed power ratio, the increased relaxation time is equally suppressing overall MI.
