摘要

本文利用激光二极管的直流驱动电流，设计了一种基于激光二极管直接调制和光纤射频滤波器的可调谐射频光电子振荡器。光纤射频滤波器的使用允许在频率阶跃等于反馈回路固有模式或无滤波器频谱范围的离散振荡频率下的30 dB侧模抑制比。实验结果验证了理论分析的正确性

Tuning of an RF Optoelectronic Oscillator

In this paper tunable RF optoelectronic oscillator based upon direct modulation of laser diode and an optical fiber RF filter is demonstrated using the dc driving current of the laser diode. The use of the optical fiber RF filter allows a sidemode suppression ratio of 30 dB at discrete oscillation frequencies with frequency step equals to the intrinsic modes of the feedback loop or the filter free spectral range. Experimental results are presented to verify the theoretical analysis
