“…In the following the minimal transmission angle is referred to as 0° and the angle of maximal transmission is 100°. In our previously reported works used all-polarization control cavities [25][26][27]33] we experimentally found that the regimes of mode-locking operation depend on the polarization state in CW mode, before mode-locking is started. We will refer to this state as the initial polarization state.…”

In the present work we demonstrate a novel single-soliton ultra-low pulse repetition frequency passively modelocked erbium-doped fiber laser. We mitigate the residual linear birefringence of fiber by fiber twist to achieve a strict control of polarization. For mode-locking the nonlinear polarization rotation (NPR) was used. Special technique was applied to reduce the overdriving of NPR that allows the generation of single soliton in ultra-long cavity. The strict control of polarization yields a stable relation between the polarization state of the pulses propagating in the cavity and the regimes of generation. A 192.12-kHz train of soliton pulses was obtained with pulse duration of 4.7 ps at 1560.1 nm, the average power was 29 μW and the estimated peak power was ̴ 30.8 W with an energy of 150.9 pJ.

“…These properties of the twisted fiber allow a strict control of the polarization state in the laser cavity. Recently, we demonstrated stable and predictable switching between different regimes of generation in a mode-locked fiber ring laser where fiber twist was used to cancel residual birefringence [25,26].…”

“…To have total polarization control in the cavity, it is important to mitigate the linear birefringence in the Erbium-doped fiber amplifier (EDFA) to preserve the polarization state of the light. The model includes a double-pass EDFA as presented in [17][18]. The simulated gain was Erbium-doped fiber with a central peak centered at 1550 nm.…”

“…In recent years, Kuzin et al [17][18] have been dedicated to performing the experimental investigation of passive mode-lock nonlinear polarization rotation (NPR) fiber lasers with strict polarization control. In these investigations, it was possible to show the initial conditions required to generate different types of pulses in a controlled and reproducible manner.…”

We report the numerical study of the polarization properties of a net anomalous dispersion ring cavity with total polarization control. As a mode locker, we use the nonlinear polarization rotation (NPR) method. The initial ellipticity and azimuth were fixed to 13° and 0°, respectively. The simulations, made by the split-step Fourier method, show changes in polarization with respect to initial conditions, after the mode-lock process such as previously reported in the literature. It was found that polarization changes are caused by non-linear birefringence. The pulsed laser produces solitonic pulses with 0.4 ps FWHM and 240 W peak power.
