论文摘要
我们提出了一种基于光学频率梳的稳定射频极化调制的方法。两个具有相同重复率和不同偏移频率的脉冲列车会产生在偏移频率差下调节的任意极化状态。在FREP/2处的调制频率证明了极化调制的长期稳定性。还证明在FREP/4处的调制显示了该技术的灵活性。我们采用电延迟线来微调构成时间依赖性调制的极化状态。
We propose a method to generate stabilized radio-frequency polarization modulation based on optical frequency combs. Two pulse trains with the same repetition rate and different offset frequencies generate arbitrary polarization states that are modulated at the offset frequency difference. Long-term stability of the polarization modulation is demonstrated with the modulation frequency at frep/2. Modulation at frep/4 is also demonstrated to show the flexibility of the technique. We employ an electrical delay line to fine-tune the polarization states that constitute the time-dependent modulation.
