“…Operation of erbium-doped fiber lasers passively mode locked by either conventional NPR technique or SESAM in various cavity dispersion regimes were intensively investigated previously [14,15,16,17,18,19,20,21,22,23]. It is well-known that in the anomalous cavity dispersion regime, the nonlinear Schrodinger equation type of soliton will be formed in the fiber laser, due to the natural balance between the anomalous cavity dispersion and fiber nonlinear optical Kerr effect, while in the large normal cavity dispersion regime, a dissipative soliton whose dynamics is described by the extended Ginzburg-Landau equation will be formed [24], and the formation of the soliton is a result of the mutual nonlinear interaction among the normal cavity dispersion, fiber Kerr nonlinearity, and the effective laser gain bandwidth filtering [23], moreover, in the regime of near zero cavity dispersion, the so called dispersion-managed solitons will be formed, which have a characteristic Gaussian pulse profile and power spectrum [25].…”

Soliton operation and soliton wavelength tuning of erbium-doped fiber lasers mode locked with atomic layer graphene was experimentally investigated under various cavity dispersion conditions. It was shown that not only wide range soliton wavelength tuning but also soltion pulse width variation could be obtained in the fiber lasers. Our results show that the graphene mode locked erbium-doped fiber lasers provide a compact, user friendly and low cost wavelength tunable ultrahsort pulse source.Graphene mode locked wideband tunable output spectra from 1570 nm to 1600 nm

“…Solitons formed in fiber lasers are governed by the Ginzburg-Landau equation (GLE), which has predicted several pulse operation states. Harmonic mode locking [19], bunch-state pulses [20], and bound-state solitons [21,22] have been verified both experimentally and numerically. Generally, conventional solitons in fiber lasers exhibit hyperbolic-secant intensity profiles and spectral sidebands [23].…”

The formation and evolution of dual-wavelength solitons in passively mode-locked fiber soliton lasers are investigated both numerically and experimentally. By solving the Ginzburg-Landau equation and taking the gain profile into account, mode-locked soliton emissions at 1532 and 1555 nm are achieved simultaneously. Numerical results show that the two solitons exhibit the same intensity and duration, indicating that the dual-wavelength pulses possess the soliton energy quantization effect. In the process of pulse-pulse collisions, two solitons pass through each other and maintain their properties, qualitatively distinct from single-wavelength solitons that never overlap each other. The dual-wavelength mode-locked operation evolves into single-wavelength mode locking with the decrease of the pumping strength. The dual-peak gain spectrum of erbium-doped fiber and the birefringence-induced cavity filtering effect play crucial roles in the formation of dual-wavelength solitons. Numerical results agree well with analytical solutions and experimental observations. Our study provides an optional method of measuring the fiber dispersion by means of the dual-wavelength solitons.

“…However, the pulse repetition rate is only at 8.6 MHz. Liu et al reported the generation of a stable passive 23 rd harmonic mode-locked pulse train at 230 MHz with a pulse width of 0.44 ps [45]. Despite the fact that those NPR based passively mode locked fiber lasers can produce ultrashort femtosecond pulses, they suffer from the drawback of low repetition rate (only at MHz level) with respect to the total cavity length, which limits their applications in high speed fiber optic communications.…”

Mode locked pulse generation has been reported using both active and passive mode locking schemes. Active mode locking technique has been proven to be an effective way to generate high-repetition-rate pulses by incorporating a modulator inside the laser cavity. Compared to actively mode locked lasers, passively mode locked lasers can generate pulse train at ultrashort pulse width but with relatively lower repetition rate. Thus, it is a brilliant idea to build a hybrid mode locked system combining both active and passive mode lockers. In this review, several hybrid mode locked fiber ring laser systems are discussed and summarized. Hybrid mode locking is a promising method to generate high speed ultrashort optical pulses for fiber-optic telecommunication system.
