摘要
研究了强双折射光纤中沿偏振主轴入射的超短光脉冲压缩效应。当考虑三阶色散效应时 ,三阶色散与光纤非线性相互作用能增强一偏振光脉冲的压缩而抑制另一偏振光脉冲的压缩。正三阶色散增强慢孤子压缩 ,负三阶色散增强快孤子压缩。三阶色散参量越大 ,脉冲压缩效果越明显。
Compression of ultrashort pulses in strongly birefringent optical fibers is studied. When the third order dispersion is considered, one of polarization pulse compression is enhanced and the other polarization pulse compression is suppressed due to the interaction of the third order dispersion and nonlinear effects. Slow soliton is compressed in the fiber with positive third order dispersion, fast soliton is done in the fiber with negative third order dispersion. The large value of third order dispersion parameter, the more evident the compression effect.
