We demonstrate that the phase shift of a reference injection-locked optoelectronic oscillator (OEO) varies as the change of its fiber delay over a long period of time. The dynamic variation of the fiber delay is monitored using an injected probe signal and is compared with the phase shift. With actively stabilized fiber delays according to the monitored data, the long-term frequency stability of the reference injection-locked OEO is evaluated.
我们证明了参考注入锁定光电振荡器（OEO）的相移随其光纤延迟的长时间变化而变化。使用注入的探测信号监测光纤延迟的动态变化，并与相移进行比较。根据监测数据主动稳定光纤延迟，可以评估参考注入锁定 OEO 的长期频率稳定性。
