摘　　要：光电振荡器是拥有闭合光电反馈回路的微波光子信号源。借助微波光子学大带宽、低损耗等优势,光电振荡器可实现高中心频率、超低相位噪声的微波信号产生,从而克服传统电学信号源面临的频率和相位噪声瓶颈,应用于雷达、通信、测量和电子对抗等现代电子信息系统。综述近些年来涌现的新型光电振荡器,介绍可实现无滤波器单模振荡的宇称-时间对称光电振荡器、快速扫频的傅里叶域锁模光电振荡器、参量锁相的光电参量振荡器、频率随机变化的宽带随机光电振荡器、自发跳频的孤子光电振荡器、脉冲型的主动和被动锁模光电振荡器以及小型化的集成光电振荡器等,并探讨这些新型光电振荡器的应用和未来发展趋势。Significance Signal sources are key elements of modern electronic information systems such as radar,communication,measurement,and electronic warfare systems.High-performance microwave signal sources with high center frequency and ultra-low phase noise are essential to meet the rapid development trends of large bandwidth and high sensitivity in modern electronic information systems.However,achieving high center frequency and ultra-low phase noise simultaneously is very challenging for conventional electrical signal sources.Ultra-low phase noise is generally achievable at low center frequencies for conventional electrical signal sources.Although high center frequency microwave signals can be obtained by multiplying a low-frequency signal,the phase noise will also be deteriorated by a factor of 20log10N in the frequency multiplication process.An optoelectronic oscillator(OEO)is a microwave photonic signal source with a close optoelectronic feedback loop.High center frequency and ultra-low phase noise can be achieved simultaneously,which breaks the frequency and phase noise bottlenecks of conventional electrical signal sources.The high center frequency is obtained with the help of broadband optoelectronic devices in the OEO loop,whose bandwidth is as large as tens of GHz.The ultra-low phase noise is enabled by using low-loss or high-Q-factor energy storage elements,such as low-loss optical fiber.Moreover,the phase noise of the OEO can be independent of the center frequency according to the Yao-Maleki model,thus ultra-low phase noise can be maintained for high center frequencies and the OEO can find a wide range of applications in modern electronic information systems.A series of novel OEOs have been proposed and demonstrated in recent years,including parity-time symmetric OEO that achieves single-mode oscillation without filters,frequency scanning Fourier domain mode-locked OEO that overcomes mode building time limitations,optoelectronic parametric oscillator(OEPO)that enables phase-locked stable oscillation,broadban
