摘要
提出并验证了一种借助于光纤环级联结构实现边模抑制与选择的光电振荡器设计方案。采用长光纤双环路结构实现部分边模抑制,利用光纤环级联结构构成微波光子带通滤波器对振荡模式进行精细选择,可得到低相位噪声和高频谱纯度的高频微波信号。
A design scheme of optoelectronic oscillator with side-mode suppression and selection by means of cascaded optical fiber rings is presented and validated. The long-fiber double-loop structure is used to achieve partial side-mode suppression, the oscillation mode is finely selected by the microwave photonic band-pass filter which is fabricated by cascaded optical fiber rings structure, and the high-fi：equency microwave signal with low phase noise and high spectral purity can be obtained.
