Optoelectronic oscillators have been extensively investigated for military and civilian applications owing to their low phase noise and adjustable frequency. However ,they exhibitunstable output-signal frequencies ,which limits their application and widespread use in engineering. Hence ,this study investigates the frequency-drift mechanism of optoelectronic oscillators and proposes a frequency-stabilization method for optoelectronic oscillators based on photoelectric hybrid feedback control. This method can realize a stable output under a specific oscillation frequency of a photoelectric oscillator while ensuring low phase noise from the optoelectronic oscillator. Experimental test results show that the stability of the photoelectric oscillator can reach 5. 6× 10- 12 daily ,which satisfies the application requirement for frequency stabilization in engineering.
