摘要

在光电振荡器(OEO)系统中，保持频率尽可能恒定是至关重要的。电光调制器(EOM)是该系统的关键部件，对系统的稳定性有很大影响。EOM的特点是其电压和光输出传递函数，不幸的是，该传递函数在时间期间经历漂移，导致EOM特性的变化，最终导致振荡频率的漂移。开发了一种用于控制电磁辐射的双仪表系统。第一部分是EOM温度控制。通过使用该部件，在一小时的持续时间内，OEO频率漂移可以减少1.39倍。仪器系统的第二部分用于补偿EOM传递函数的漂移。当这两部分同时工作时，一小时的频率漂移减小系数可达3.44。这些结果证明了补偿方法的有效性。

Improving the operation of optoelectronic oscillator by stabilizing the electrooptic modulator

In an optoelectronic oscillator (OEO) system, it is crucial to keep the frequency as constant as possible. Electrooptic modulator (EOM) is a key component in this system having a big influence on OEO stabilization. The EOM is characterized by its voltage to optical output transfer function which unfortunately undergoes a drift during time leading to changes of the EOM characteristics and finally to a drift of the oscillation frequency. A twofold instrumentation system has been developed for controlling the EOM. Its first part is dedicated to the EOM temperature control. By using this part, the OEO frequency drift can be reduced by a factor 1.39 for one hour duration. The second part of the instrumentation system is used for compensating the drift of the EOM transfer function. With these two parts operating simultaneously, the frequency drift reduction can reach a factor up to 3.44 for one hour. These results demonstrate the efficiency of the compensation method.
