“…In summary, the experimental verification of dark solitons in optical fibers necessitates a comprehensive approach integrating pulse shaping techniques, nonlinear optical effects, and theoretical modeling. By harmonizing these methodologies, researchers can elucidate the fundamental properties and dynamics of dark solitons, advancing our understanding of nonlinear optics and optical communication technologies [49][50][51][52][53][54].…”

This investigation focuses on the construction of novel dark and singular soliton solutions for the Hirota equation, which models the propagation of ultrashort light pulses in optical fibers. Initially, we employ a wave variable transformation to convert the physical model into ordinary differential equations. Utilizing extended rational sinh–cosh and sine–cosine techniques, we derive an abundant soliton solution for the transformed system. By plugging these explicit solutions back into the wave transformation, we obtain dark and singular soliton solutions for the Hirota equation. The dynamic evolution of dark soliton profiles is then demonstrated, with a focus on varying physically significant parameters such as wave frequency, strength of third-order dispersion, and wave number. Furthermore, a comprehensive analysis is examined to elucidate how the dark and singular soliton profiles undergo deformation in the background influenced by these arbitrary parameters. The findings presented in this study offer valuable insights that could potentially guide experimental manipulation of dark solitons in optical fibers.

“…In 2022, Tang et al found the bound state solitons in the MLFL based on GIMF-step-index multimode fiber (SIMF) -GIMF SA [26]. In general, most of the bound state solitons in fiber lasers are so-called as bound state soliton pair [26][27][28][29][30], as the pulses within both sides of the pair have the same width and intensity. Also, the time separation of the tightly bound solitons is narrower than that of the loosely bound solitons [27][28][29][30][31][32][33].…”

Also, the time separation of the tightly bound solitons is narrower than that of the loosely bound solitons [27][28][29][30][31][32][33]. However, the all-fiber structured SA may have problems, such as a relatively small signal-to-noise ratio (SNR), low stability of mode-locking as well as high level of continuous wave (CW) component under mode-locking.…”

A new all-fiber structured saturable absorber, consisting of graded index multimode fiber-no-core fiber-graded index multimode fiber (GIMF–NCF–GIMF), in a passively mode-locked erbium-doped fiber laser is proposed and demonstrated. The conventional solitons with a center wavelength of 1575.5 nm, a pulse width of 707 fs, and a signal-to-noise ratio of 66 dB are generated at the repetition frequency of 18.919 MHz. The different lengths of each part of the saturable absorber (SA) can usually allow the fiber laser system to reach mode-locking, which shows that the length limits on this SA can not be quite as serious. Meanwhile, by only adjusting the polarization controller, tightly bound solitons and loosely bound solitons can be readily generated. The pulse trains of tightly bound solitons exhibit a separation of 1.52 ps, a pulse width of ∼850 fs, and centered at 1573 nm, whereas the pulse separation of loose bound solitons are from 23 ps to 58 ps, which shows wide variations of the time dispersion. More importantly, it is found that tightly bound solitons and loosely bound solitons can exist simultaneously for higher-order solitons, for the first time to the best of our knowledge. Such an SA is easy to fabricate, highly stable and of low cost, and has high potential in ultrafast photonics.

“…Stratmann theoretically studied the generation of chains of temporal dark solitons in a dispersion-managed fiber [8]. A dark pulse was generated in a dispersion-managed fiber ring laser by Li in 2011 [9]. Bright-dark soliton pairs had also been observed in Kerr-type nonlinear media [10][11][12] and optical fiber systems [13].…”

The evolution of dark–dark soliton pairs is numerically investigated in a dispersion managed erbium-doped fiber ring laser. It is found that the fluctuation of the background, the sideband intensity of the optical spectrum, the distance and the width of dark–dark soliton pairs are related to the orientation of the polarization controllers and the pump power of the fiber ring laser. The evolution of dark–dark soliton pairs is caused by the modulation instability and the balance between gain and loss in the fiber ring laser.
