Raman-induced polarization stabilization of vector solitons in circularly birefringent fibers

Abstract: Vector soliton propagation in circularly birefringent fibers was studied by perturbation analysis and numerically. The results show that in presence of both Raman self-frequency shift and group velocity difference between circularly polarized components the Raman cross-polarization term causes an energy transfer from the slower to the faster circular component of vector solitons. This effect leads to polarization stabilization of circularly polarized vector solitons.

“…The ellipticity of the highest soliton generated in the process of pulse breakup at different noise imposed on the pulse was also calculated. The equations and the procedure described before were used [7]. The equations are taken into account the difference of group velocity of orthogonal circularly polarized components and vectorial nature of the Raman Figure 10.…”

“…(3) and separate the real part from the imaginary one. The exact solutions of chirped dark vector quasi-solitons can be determined by the following constraints: ---------------------------------------------------------= (13) (14) Considering the heterogeneity of fibers, it is necessary to adopt the variable coefficient form to set the fiber parameters, which can be assumed in the following form: (15) where β 0 is the ideal birefringent fiber parameter, C 1 represents the amplitude of the fiber parameter fluctuation, which is a tiny amount, δ 1 represents the period of the change of fiber parameters, δ 2 is a real constant. And then one obtains,…”

“…In the last few years, many researches on it have gained much more attention. 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].…”
