We present a novel broadband divide-by-2 microwave photonic injection locking frequency divider (ILFD) based on a dual-loop optoelectronic oscillator (OEO). In the proposed scheme, a tunable microwave photonic filter is used to replace the traditional electrical filter, which makes sure a large tuning range of the ILFD. The microwave photonic ILFD whose center frequency tracks the tunable frequency of the free-running OEO, links up with every single locking range together. Thus the frequency range is only determined by the tunable OEO. In the experiment, a wide operating frequency range from 4.51 GHz to 34.88 GHz is realized. Furthermore, a divide-by-3 ILFD is experimentally demonstrated with the help of a frequency mixer.

基于可调谐光电振荡器的微波光子注入锁定分频器

我们提出了一种基于双环光电振荡器（OEO）的新型宽带2分频微波光子注入锁定分频器（ILFD）。在所提出的方案中，可调谐微波光子滤波器被用来代替传统的电滤波器，这确保了ILFD的大调谐范围。微波光子ILFD的中心频率跟踪自由运行的OEO的可调频率，并将其与每个单个锁定范围链接在一起。因此，频率范围仅由可调OEO确定。在实验中，实现了从4.51 GHz到34.88 GHz的宽工作频率范围。此外，借助混频器，实验证明了3分频ILFD。
