In order to develop a practical all-optical polarization control tool, according to vector stimulated Raman scattering theory and random birefringence effect of optical fibers, a scheme of all-optical polarization control was proposed based on bi-propagating dual-order Raman pump. After the establishment of the theoretical model solved by rigorous numerical method, the optimal design of the polarization control scheme was completed. The results show that when signal wavelength is 1550nm, signal power is 0.1mW, pump light P1 and P2 power are 1W and 4W, and their polarization states are (0, 1, 0), fiber length is 3km, the degree of polarization of signal light could be more than 0.85, and the intensity fluctuations of signal light are less than 35%. The proposed method is effective to reduce the power of the interacting light wave, weaken the intensity noise of output optical signal and improve the degree of polarization of optical signals.
