Influence of quintic nonlinearity on interaction of chirped ultrashort laser pulses

More Information
  • Based on the model of the high-order nonlinear complex Ginzburg-Landau equation including quintic nonlinearity, the interaction of chirped ultrashort laser pulses was numerically studied by using split-step Fourier transform method. The results show that the quintic-order nonlinear terms are important for the interaction between neighboring solitons, even small variation could change the transmission characteristic. The interaction among them can be well suppressed by appropriately selecting the coefficient of the quintic-order nonlinear and the transmission bit-rate in optical telecommunications is increased. The further simulation shows that two solitons preserving long-distance transmission can be achieved when the initial separation of neighboring solitons is equal to 6.8 and the quintic nonlinear coefficient value is equal to -0.001.
