摘要
对光克尔脉冲净化器中,不同双折射度光纤中相干耦合效应对光克尔脉冲净化器透射率以及输出脉冲的时间波形、光谱以及脉冲自身透射率等特性进行了模拟分析。结果表明:高双折射光纤中,两偏振光的相干耦合效应影响可以忽略;普通单模光纤中两偏振光的相干耦合导致透射率幅值变化在±1%左右;低双折射光纤中相干耦合效应影响较大,且相干耦合效应对输出脉冲时间波形与光谱以及脉冲自身透射率曲线都有一定影响。
Abstract
In optical Kerr pulse clenear, the used fibers with different mode birefringence degrees can produce different coherent coupling degrees at the two polarization light. Different coherent coupling degrees will affect the output of the optical Kerr pulse clenear. The pulse, spectrum, transmissivity of pulse itself and system with different mode birefringence degrees are simulated. For high birefringence fiber, the coherent coupling effect at the two polarization light can be neglected. For common single mode fiber with medium birefringence degree, the change of pulse′s transmissivity is about ±1%. But for low birefringence fiber, the infection of the coherent coupling is much higher, and the coherent coupling affect also has much higher infection for the temporal and spectral shape and the transmissivity of the pulse itself.
