We demonstrate optical to radio frequency (RF) locking technique using all-fiber phase shifter. Phase shift at 1030 nm was achieved by pumping Er-doped fiber incorporated in the resonator. Pump induced refractive index change was fast enough to stabilize optical pulse repetition rate of ultrafast Yb-doped fiber oscillator and achieve sub-200 fs timing jitter. We also investigate the source of phase noise in soliton fiber oscillators and provide guidelines how to further reduce timing jitter.

超快镱基SESAM锁模光纤振荡器的全光重复率稳定方法

我们展示了使用全光纤移相器的光学到射频 (RF) 锁定技术。1030 nm 的相移是通过泵浦掺入谐振器的掺铒光纤实现的。泵浦引起的折射率变化足够快，可以稳定超快掺镱光纤振荡器的光脉冲重复率，并实现低于 200 fs 的定时抖动。我们还研究了孤子光纤振荡器中的相位噪声源，并提供了如何进一步降低时序抖动的指南。
