A photonic method to generate pulse trains with double repetition rate in FM actively mode-locked fiber-optic parametric oscillator (FOPO) has been proposed and experimentally demonstrated. Pulse trains can exist at either of the two extremums of phase modulation, which can be controlled by tuning an intra-cavity polarization controller (PC) before a phase modulator. Moreover, the pulse formation and spectral characteristics of the proposed FOPO are investigated. By continually rotating the intra-cavity PC, two optical pulse trains corresponding to two different mode-locked states are generated simultaneously. In the experiment, 8, 10, 12 and 14GHz pulse trains are generated using RF drive frequencies of around 4, 5, 6 and 7GHz, respectively.
提出并通过实验证明了一种在调频主动锁模光纤参量振荡器（FOPO）中产生具有双倍重复率脉冲序列的光子方法。脉冲序列可以出现在相位调制的两个极值处的任意一个，这可以通过在相位调制器之前调谐腔内偏振控制器（PC）来控制。此外，还研究了所提出的FOPO的脉冲形成和光谱特性。通过连续旋转腔内PC，同时产生对应于两种不同锁模状态的两个光脉冲序列。在实验中，分别使用约4、5、6和7GHz的射频驱动频率产生了8、10、12和14GHz的脉冲序列。
