Abstract

The soliton-sinc pulses are a recently proposed new type of pulse that has the properties of the Nyquist pulses and the solitons. The soliton-sinc pulses are robust to nonlinear signal distortions due to the preservation of the same oscillatory structure as the Nyquist pulse. The soliton-sinc pulses hold fascinating promise for applications in optical communications, and the latest research in optical cavities has realized soliton-sinc pulses. We investigate the propagation dynamics of soliton-sinc pulses in the presence of higher-order effects, including fourth-order dispersion, self-steepening, and Raman effects. Numerical results show that under normal fourth-order dispersion, one radiates dispersion waves, while under anomalous dispersion the soliton-sinc pulse splits. The intensity of the radiative dispersion wave and the intensity of the pulse splitting is governed by the bandwidth of soliton-sinc pulse. In the presence of self-steepening effects, the number of soliton-sinc pulse splits can be effectively controlled by the bandwidth. Simultaneously, under the influence of the Raman effect, the Raman effect becomes more obvious with smaller bandwidth restrictions. These results demonstrate the propagation dynamics of soliton-sinc pulses under higher-order dispersion and nonlinear effects, which have practical applications for pulse control and optical communications in optical fibers.
