摘 要: 应用类明孤子在单模光纤中非线性传输特性的微扰理论,研究了光纤Raman散射对类明孤子传输特性的影响,导出了类明孤子参数演化的动力学方程。结果表明:光纤Raman散射微扰对类明孤子脉冲位置、频率和相位参数有影响,而对类明孤子脉冲振幅、脉宽、啁啾参数无影响。 The Influence of optical fiber Raman scattering on bright oliton-like propagation properties in investigated by using perturbation theory on it's propagation properties in monomode optical fibers,and the dynamics equations for it's parameters is derived.The result shows that optical fiber Raman scattering effects on the position,frequency and phase,but does not on the amplitude,pulse width and chirp of the bright soliton-like pulse.
