【摘要】：分析比较了基于锁相环技术和基于注入锁定技术的两种光电振荡器的特性,推导了两种光电振荡器的噪声传递函数,并进行了实验验证,得出了这两种技术应用于光电振荡器的相似性和各自的优缺点.由于光纤对温度的高敏感性,采用这两种技术的光电振荡器都存在着易失锁的问题.为解决这一问题,分别分析了两种光电振荡器输出信号与参考信号间的相位关系,基于此关系设计了锁定状态监测和反馈系统,并实验验证了系统的有效性.
[Abstract]:The characteristics of two kinds of optoelectronic oscillators based on phase-locked loop technology and injection locking technique are analyzed and compared. The noise transfer function of two kinds of optoelectronic oscillators is derived and verified by experiments.The similarities, advantages and disadvantages of the two techniques applied to the optoelectronic oscillator are obtained.Because of the high sensitivity of optical fiber to temperature, the optoelectronic oscillator using these two techniques is easy to be locked.In order to solve this problem, the phase relationship between the output signal and reference signal of two kinds of optoelectronic oscillator is analyzed, based on which the locked state monitoring and feedback system is designed, and the effectiveness of the system is verified by experiments.
