超低抖动光脉冲源在光通信、光采样和计量等领域有着广泛的应用。本文报道了一种采用非保偏器件和掺铒光纤放大器的耦合光电子振荡器，该振荡器产生的9.4GHz微波信号在10 ~ 100 kHz偏移处相位噪声为-150dBc/Hz，光脉冲抖动为2fs（在100 ~ 100 kHz范围内积分）。据我们所知，这是在相同的频率范围内报告的最低相位噪声和时间抖动的锁模激光系统
Ultralow jitter optical pulse sources are much needed in optical communications, optical sampling, and metrology applications. We report a coupled optoelectronic oscillator employing nonpolarization-maintaining components and an erbium-doped fiber amplifier that generates 9.4-GHz microwave signals with -150-dBc/Hz phase noise at 10- to 100-kHz offset, and 2-fs jitter (integrated in 100-Hz to 100-kHz range) optical pulses. To our knowledge, this is the lowest phase noise and time jitter reported in the same frequency range for such mode-locked laser-based systems
