提出并演示了采用外注入法布里-珀罗激光二极管（FP-LD）的光电振荡器产生宽带和频率可调微波信号。通过外部注入，FP-LD作为可调谐的高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节FP-LD的纵向模式来实现频率调谐。进行了实验；产生频率在6.41 ~ 10.85 GHz范围内可调的微波信号。研究了所产生的微波信号的相位噪声特性。
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.
