光脉冲定时控制对于稳定光时分复用器等极密集的光信号处理设备非常重要。实现了一种利用光双脉冲及其互相关信号实现亚皮秒脉冲定时监测和稳定的模块。由于光纤温度变化而引起的45ps的定时漂移在没有高速电子电路的情况下稳定在0.8ps以内。由于其稳定的双脉冲距离和相关测量机制，该模块具有良好的时间分辨率，优于0.1ps。
Optical pulse timing control is very important for stabilizing extremely dense optical signal handling devices such as optical time-division multiplexers. We realize a module that offers subpicosecond pulse-timing monitoring and stabilization through the use of optical double pulses and their cross-correlation signals. A 45-ps timing drift due to the temperature change of a fiber is stabilized to within 0.8 ps without high-speed electronic circuits. This module has excellent time resolution, better than 0.1 ps, due to its stable double-pulse distance and correlation measurement mechanism.
