近年来，光电振荡器（OEO）作为高性能微波源引起了广泛关注。得益于光学延迟线提供的高质量因素（Q因子），OEO可以生成具有超低相噪声的光谱纯微波信号。在过去的二十年中，已经证明了实现单频微波信号生成的OEO体系结构的各种方法。由OEO生成的微波信号播种，已经证明了复杂的微波波形的产生，可用于雷达和通信系统等应用中。 OEO还已被证明可以在不同应用中执行其他特定功能，包括光脉冲和频率梳子产生，光学传感，低功率微波信号检测和光信号处理。本文回顾了过去二十年来OEO的发展。据报道，具有单一集成的光子零件和射频子小节的集成的OEO是OEO整体整合的一个有希望的例子。还描述了OEO的关键特征和OEO整合的未来发展的前景。
The optoelectronic oscillator (OEO) has attracted a great deal of attention in recent years as a high-performance microwave source. Thanks to the high quality-factor (Q-factor) provided by the optical delay line, the OEO can generate spectrally pure microwave signals with ultralow phase noise. Various approaches for realization of OEO architectures for the generation of single-frequency microwave signals have been demonstrated in the past two decades. Seeded by the microwave signal generated by OEO, the generation of complex microwave waveforms has been demonstrated, which can be used in applications such as radar and communication systems. OEO has also been demonstrated to perform other specific functionalities in different applications, including optical pulses and frequency comb generation, optical sensing, low-power microwave signal detection, and optical signal processing. This paper reviews the developments of OEO over the past two decades. An integrated OEO with monolithically integrated photonic parts and radio frequency subsections is reported as a promising example toward the monolithic integration of OEO. Key features of OEO and prospects for future development of the integration of OEO are also described.
