依托微波光子学的发展,光电振荡器采用光电反馈环路技术,将激光能量转换为微波信号能量,摆脱了传统微波振荡器随频率升高相噪性能会降低的限制,能以光、电两种形式输出稳定的低噪声信号,成为一种新型的高质量微波信号源。光电振荡器不仅具有一定的可调谐性能,而且能够产生频率从几GHz到上百GHz、Q值高达1010的电信号,具有广阔的应用前景,受到了广泛的关注。文章阐述了光电振荡器的研究现状,对光电振荡器的相位噪声、边模抑制、频率稳定性、频率可调谐性、高频输出、集成化等方面进行简要概括。
Relying on the development of microwave photonics, the photoelectric oscillator uses photoelectric feedback loop technology, the laser energy is converted to microwave signal energy, out of the traditional microwave oscillator with the frequency of noise reduction will reduce the performance limits, to light and electricity two Stable form of low-noise signal output, a new type of high-quality microwave signal source. The optoelectronic oscillator not only has a certain tunable performance, but also can generate electrical signals with frequency from several GHz to hundreds of GHz and Q value up to 1010, which has broad application prospect and received widespread attention. This paper describes the research status of optoelectronic oscillators and briefly summarizes the phase noise, side mode suppression, frequency stability, frequency tunability, high frequency output and integration of optoelectronic oscillators.
