利用耦合非线性薛定谔方程分析了光脉冲在超高偏振模色散光纤中传输时 ,偏振模色散引起脉冲分裂。并用基模的两正交偏振分量耦合走离解释了脉冲分裂的成因。利用偏振模色散为 2 37.95 ps/km1/ 2 的光纤进行了实验验证。
The coupling of nonlinear Schrödinger equation was used to analyze the pulsed splitting caused by polarization mode dispersion when the optical pulse was transmitted in an ultrahigh polarization mode dispersion fiber. And the coupling of the two orthogonal polarization components of the fundamental mode to explain the cause of the pulse splitting. Experiments were performed on fibers with polarization mode dispersion of 2 37.95 ps / km1 / 2.
