论文摘要
光纤中极化模式色散（PMD）的非转录和动态性质可能是准确的时间和频率传递的问题。在这里提出了一种简单的被动解决方案，该解决方案基于与交替正交极化的传输光脉冲。快速和确定性的极化调制意味着，PMD噪声远离感兴趣的频率并在接收器的Faraday镜面反射时，脉冲在返回发射器时具有明确的极化，这有助于稳定的光学相位检测和纤维相位补偿。在使用模式锁定激光和简单脉冲交叉的开环测试设置中，偏振模式分散剂被证明减少了两个以上的数量级
The non-reciprocal and dynamic nature of polarization mode dispersion (PMD) in optical fibers can be a problem for accurate time and frequency transfer. Here a simple, passive solution is put forward that is based on transmitting optical pulses with alternating orthogonal polarization. The fast and deterministic polarization modulation means that the PMD noise is pushed far away from the frequencies of interest and upon reflection from a Faraday mirror at the receiver, the pulses have a well defined polarization when they return to the transmitter, which facilitates stable optical phase detection and fibre phase compensation. In an open-loop test setup that uses a mode-locked laser and a simple pulse interleaver, the polarization mode dispersion is shown to be reduced by more than two orders of magnitude
