随机双折射单向旋转光纤中的单泵浦参量放大
Single pump, parametric amplification in randomly-birefringent, unidirectionally spun fibers
摘要：
通过数值求解偏振模色散与宽带和窄带单泵浦光纤参量放大器的相互作用方程，系统地研究了偏振模色散对光纤参量放大器的影响。非线性偏振旋转被证明是一个相关的效果，可以增加增益随机性时，它混合偏振模色散。在单向旋转光纤中，信号泵浦对准可以大大增加，增益增强。然而，尽管增强的对准，大的偏振模色散相位失配的相互作用和增益降低到零。
英文摘要：
A systematic study of the effects of polarization mode dispersion on broad-band and narrow-band, single pump, fiber parametric amplifiers is realized through numerical solutions of the equations governing the interaction. The nonlinear polarization rotation is shown to be a relevant effect that can increase gain randomness when it mixes with polarization mode dispersion. In unidirectionally spun fibers the signal-pump alignment can be highly increased and the gain enhanced. However, in spite of the enhanced alignment, large polarization mode dispersion phase-mismatches the interaction and the gain decreases to zero.
