摘　　要：光电振荡器应用了光电混合的技术手段,通过光纤储能和延迟的方法可实现频率精度、稳定度、相位噪声都显著优于常规微波介质振荡器的一种新型振荡源。简要介绍了光电振荡器的基本原理和研究现状,并应用内调制激光器和长光纤环结构进行了实验研究,得到了相位噪声优于-112 dBc/Hz@10 kHz、线宽<1 Hz的高性能微波信号输出。The optoelectronic microwave oscillator (OEO) is based on optoelectronic technology,which applie optical energy storage elements and optical delay method to achieve a novel oscillator source with better performances than the normal microwave dielectric oscillator in the characters such as spectral purity,stability and phase noise.In this paper,we simply introduce the principle of the OEO and the development tendency.Therefore, an experiment is carded out in a new scheme applying direct-modulated semiconductor laser and long fiber loop structure.The experiments results show that local oscillation output with good performances is achieved where its' phase noise and line width is lower than-112 dBc/Hz@10 kHz and small than 1 Hz respectively.
