A time-domain convolution model is proposed to study the oscillation dynamics in the injection-locked optoelectronic oscillator (OEO). The model has the ability to calculate multiple characteristics of the oscillation signal, such as the spectrum and the phase noise. Based on the model, the injection locking, the frequency pulling and the asymmetrical spectrum generation phenomena are numerically simulated in success. The simulation results fit in with the experimental results, indicating that the proposed model accurately describes the oscillation dynamics in the injection-locked OEO. In addition, the building-up process of the oscillation signal in the OEO is simulated. Alternating appearance of the sidebands on both sides of the primary oscillation mode is observed for the first time in the asymmetrical spectrum generation. This model is a powerful tool to study the oscillation dynamics in the injection-locked OEO.
提出了一种时域卷积模型来研究注入锁定光电振荡器（OEO）中的振荡动力学。该模型能够计算振荡信号的多个特性，如频谱和相位噪声。基于该模型，依次对注入锁定、频率牵引和非对称频谱产生现象进行了数值模拟。模拟结果与实验结果相符，表明所提出的模型准确地描述了注入锁定OEO中的振荡动力学。此外，还模拟了OEO中振荡信号的建立过程。在非对称频谱产生中首次观察到主振荡模式两侧边带的交替出现。该模型是研究注入锁定OEO中振荡动力学的有力工具。
