Wideband and frequency-tunable microwave signal generation using an optoelectronic oscillator incorporating a Fabry-Perot laser diode (FP-LD) with external optical injection is proposed and demonstrated. Through external injection, the FP-LD functions as a tunable high-Q photonic microwave filter, and the frequency tuning is realized by either tuning the wavelength of the externally injected optical light or changing the temperature to adjust the longitudinal modes of the FP-LD. An experiment is performed; a microwave signal with a frequency tunable from 6.41 to 10.85 GHz is generated. The phase noise performance of the generated microwave signal is also investigated.
提出并演示了一种利用光纤环形镜激光二极管（FP-LD）外光注入构成的光电子振荡器来产生宽带和频率可调微波信号的方法。通过外部注入，FP-LD 充当可调谐高 Q 光子微波滤波器，通过调节外部注入光的波长或改变温度来调谐 FP-LD 的纵模，从而实现频率调谐。进行了实验，产生了频率可调范围为 6.41GHz 至 10.85GHz 的微波信号。还研究了所产生的微波信号的相位噪声性能。
