“…Optical solitons play an important role in the development of versatile fields such as ultrafast laser technology [9], optical frequency combs [10], and communication systems [11]. Conventional solitons [12], stretched-pulses [13], self-similar pulses [14], and dissipative solitons [15] can be obtained from passively mode-locked fiber lasers by flexibly adjusting the intra-cavity net dispersion. In general, the dispersion management of a fiber laser is only related to the second-order dispersion, namely group velocity dispersion (GVD), while the higherorder dispersion is generally considered to have an adverse effect on the performance of soliton lasers [16].…”

We numerically investigate the influence of higher-order dispersion on the dynamics of quartic solitons in a passively mode-locked fiber laser. The simulation results show that the output pulse characteristics of the quartic soliton fiber laser are not only affected by the intra-cavity net dispersion but also related to the position of the single-mode fiber (SMF). For different intra-cavity net higher-order dispersion values, the quartic soliton undergoes multiple alternations between the stable single soliton state and pulsating state in the fiber laser, and the number and intensity of Kelly sidebands in the output pulse spectrum are significantly different. For different positions of the SMF, the dynamics of the quartic soliton are also different. In addition, we also observe two types of novel pulsation-creeping behavior and time shift. These findings provide new insights into the output characteristics of quartic solitons in fiber lasers.
