Abstract

A novel method for generating short microwave pulse trains based on a coupled signal mode-locked optoelectronic oscillator (CML-OEO) is proposed and experimentally demonstrated. In the proposed system, a coupled signal composed of two square-wave signals serves as the mode-locking signal to periodically manipulate the intracavity gain of the OEO. The pulse width of the output pulse trains can be flexibly adjusted by tuning the phase difference between the square-wave signals. This mechanism provides a means for effective pulse compression. The experimental results indicate that CML-OEO generates short microwave pulse trains with a repetition frequency of 195.005 kHz through fundamental frequency mode locking. Compared to the traditional active mode-locked optoelectronic oscillator, the CML-OEO achieves pulse compression effects of 73.0%.

基于耦合信号锁模光电振荡器的短微波脉冲序列的产生

提出了一种基于耦合信号锁模光电振荡器（CML-OEO）产生微波短脉冲串的新方法，并进行了实验验证。在该系统中，由两个方波信号组成的耦合信号作为锁模信号，周期性地控制腔内增益。通过调整方波信号之间的相位差，可以灵活地调节输出脉冲串的脉宽。这种机制为有效的脉冲压缩提供了一种手段。实验结果表明，CML-OEO通过基频锁模产生重复频率为195.005 kHz的短脉冲序列。与传统的有源锁模光电振荡器相比，CML-OEO实现了73.0%的脉冲压缩效果。
