“…The propagation of vector solitons in circularly birefringent fibers was studied by the perturbation analytically and numerically and an effect leading to the polarization stabilization of circularly polarized vector solitons was found [15]. Four types of vector solitons with different characteristics were totally observed with the usage of different lengths of polarization maintaining fibers in the highly birefringent cavity of the all-normal-dispersion ytterbium-doped fiber laser [16]. A general formalism was developed for investigating the evolution of arbitrarily polarized short pulses in a birefringent fiber.…”

In this article, we consider the coupled Ginzburg–Landau equation with variable coefficients including the nonlinear gain and obtain the exact solutions of chirped dark vector quasi-solitons via the ansatz method. Next, the propagation of chirped dark vector quasi-solitons is discussed to verify whether they can be transmitted stably in the birefringent optical fiber system. The numerical simulation shows that this can be achieved. We deeply add the small perturbation to the transmission of dark vector quasi-solitons to make the results above more general. The results further prove the correctness of our solutions.

“…It has been demonstrated that the ultrashort pulse, which is also regarded as optical soliton, would exhibit fruitful polarization dynamics in the ultrafast fiber lasers as the result of the single mode fiber (SMF) supporting the two orthogonal polarization modes. So far, various vector soliton dynamics could be observed in passively mode locked fiber lasers [22]- [34], such as polarization-locked vector solitons (PLVSs) [22]- [24], [29], [30] and polarization-rotating vector solitons (PRVSs) [31]- [33]. Being different from the PLVS, the PRVS features that the pulse intensities along the two polarization components varied periodically with the cavity roundtrip time.…”

The performance of seed laser source will have a great impact on the output pulse quality of the master oscillator power amplifier (MOPA) system. Here, we report the influence of the soliton vector features on the pulse uniformity in an all-fiber MOPA configuration. We demonstrated that, although the intensity of the dissipative soliton seed source is uniform, the intensity of the output pulse train from the MOPA will show fluctuations if the soliton polarization state is not locked, i.e., polarization-rotating vector soliton. It is found that the appearance of non-uniform pulse intensity is caused by the combination of the polarization instability and the polarization dependent gain in the polarization maintaining fiber amplifier. The obtained results indicate that the polarization evolution of seed pulsed source is critical to generation of stable pulse train from the MOPA, and also might be useful to the communities dealing with solitons and high-power pulsed fiber lasers.

“…When operated in pulse states, most of the lasers produce bright pulses. However, it was shown that dark pulses or bright-dark pulses could be formed in fiber lasers [14][15][16][17]. Shao et al reported the formation of induced dark solitary pulses in a net anomalous dispersion cavity fiber laser, where the induced solitons were formed by the cross-phase modulation (XPM) between the two orthogonal polarization components of the fiber birefringence in the laser cavity [18].…”

“…When polarization maintaining fibers are used in the cavity, a fiber laser is considered to be highly birefringent. Different from a weakly birefringent cavity, the group velocity mismatch between the two orthogonal polarization components cannot be ignored in a highly birefringent fiber laser [16].…”

Both positive-and negative-polarity Gaussian monocycle and doublet pulses, for which the pulse shapes are the first and second derivatives of Gaussian functions respectively, are generated in a ring-cavity erbium-doped fiber laser from polarization-locked vector solitons by using passive optical technology. The pulse states are switchable and are found to be the superposition of bright and dark solitons with different widths, amplitudes, time delays, polarizations, and wavelengths. Qualitative analysis of the properties of vector solitons are performed by solving coupled complex Ginzburg-Landau equations. By theoretical representing the envelopes of bright soliton by sech and dark soliton by tanh functions, the incoherent superposition of these two soliton components have simulated the experimental observations, and the underlying mechanisms on the formation for monocycle and doublet pulses are attributed to the polarization locking of bright and dark solitons. The results of tunable optical vectos solitons are compared with atomic solitons in the system of Bose-Einstein condensation. Since governing equations for soliton generation in fiber lasers and Bose-Einstein condensation have many properties in common and thus the simulation and propagation of pulsating waves may open a new route to explore the classical solitary dynamics in nonlinear optics and its quantum analogy in ultralcold fields.
