Due to the weak birefringence of single mode fibers, solitons generated in fiber lasers are indeed vector pulses and exhibit periodic parameter change including polarization evolution even when there is a polarizer inside the cavity. Period doubling eigenstates of solitons generated in a fiber laser mode-locked by the nonlinear polarization rotation, i.e., period doubling of polarization components of the soliton, are numerically explored in detail. We found that, apart from the synchronous evolution between the two polarization components, there exists asynchronous development depending on the detailed operation conditions. In addition, period doubling of one polarization component together with period-one of another polarization component can be achieved. When the period tripling window is obtained, much complexed dynamics on the two polarization components could be observed.

非线性偏振旋转锁模的光纤激光器的倍频本征态

由于单模光纤的弱双折射,光纤激光器中产生的孤子确实是矢量脉冲,即使在腔体内存在偏振器时,也会显示出周期性的参数变化,包括偏振演化。在数值上详细研究了通过非线性偏振旋转锁模的光纤激光器中产生的孤子的周期倍增本征态,即孤子的偏振分量的周期倍增。我们发现,除了两个极化分量之间的同步演化以外,还有取决于具体操作条件的异步发展。另外,可以实现一个偏振分量的周期加倍以及另一偏振分量的周期一。当获得周期三倍窗口时,
