Abstract

We demonstrate a fiber-based multiple-access ultrastable frequency dissemination scheme over an 83 km fiber link. As a performance test, we reproduce the disseminated 9.1 GHz radio-frequency modulation signal at an arbitrary point in the dissemination channel. Relative frequency stability of 7×10(-14)/s and 5×10(-18)/day is obtained. Highly synchronized frequency signals can be regenerated along the entire fiber pathway and its applications are discussed.

摘要

我们演示了一种基于光纤的多址超稳频率分发方案，该方案在 83 公里的光纤链路中运行。作为性能测试，我们在分发通道的任意点重现了分发的 9.1GHz 射频调制信号。获得了 7×10(-14)/s 和 5×10(-18)/day 的相对频率稳定性。可以沿着整个光纤路径再生高度同步的频率信号，并讨论了其应用。
