摘　　要：通过高双折射光纤中非线性耦合模传输方程,首先,利用斯托克斯参量,用庞加莱球研究分析了耦合模传输的稳定性及偏振态的演变,结果表明高双折射光纤中耦合模的传输不产生分歧现象,传输具有稳定性;其次,描述了拉曼效应对各种状态下偏振态演变规律的影响,给出了斯托克斯参量S_1,S_2与S_3的解析解及拉曼效应对偏振态的演变周期的影响.The nonlinear coupled differential equations are analyzed in high-birefringence fiber. The stability phenomena and state of polarization is discussed by extending the Stokes parameters formalism. It is shown that the transmission has no bifurcation and instability phenomena. The state of polarization （SOP） with Raman effect is in detail investigated by means of Poincare sphere. The analytical solution of Stokes parameters S1 ,S2 and S3 are presented. The period of The SoP by Roman effect is discussed.
