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.

基于光频梳的射频极化调制

我们提出了一种基于光频梳产生稳定射频偏振调制的方法。具有相同重复率和不同偏移频率的两个脉冲序列产生以偏移频率差调制的任意极化状态。调制频率为 frep/2，证明了偏振调制的长期稳定性。还演示了 frep/4 的调制以显示该技术的灵活性。我们采用电延迟线来微调构成时间相关调制的极化状态。
