| 摘 要： | 针对微波通信、雷达、电子战和导航等先进电子系统的应用发展需求,为了实现具有实用价值的极低相噪耦合微波光电振荡信号产生,提出了一种基于Sigma型光纤储能环腔架构的低相噪启钥式耦合微波光电振荡器。该方案通过Sigma型光纤储能技术消除了耦合微波光电振荡器中存在的偏振衰落问题,并且通过有源光纤环腔再生增益特性极大增强了振荡器品质因数,最终实现了10 GHz耦合微波光电振荡器的开机启钥稳定运行,起振信号在10 kHz频偏处的相位噪声达到-139.26 dBc/Hz。

| Abstract: | In order to meet the requirements of advanced electronic systems such as microwave communication, radar, electronic warfare and navigation, a turnkey coupled optoelectronic microwave oscillator with low phase noise based on Sigma-shaped fiber ring structure is proposed. In this scheme, the Sigma-shaped fiber ring structure is used to eliminate the harmful influence of the polarization-induced fading, and the quality factor of the oscillator is greatly enhanced by the regenerative gain characteristic of the active cavity. As a result, a stable 10GHz signal with low phase noise is generated as soon as the oscillator is powered on. The phase noise at 10kHz offset frequency is about -139.26dBc/Hz. |
