An opto-electronic oscillator based on guided acoustic wave Brillouin scattering in a photonic crystal fiber (PCF) stimulated by a light wave in 1 μm band is proposed and demonstrated. A short length of a homemade PCF stimulated by relatively low pump power leads to strong coupling between the pump and probe waves. The oscillation is realized in a feedback loop, in which the acoustic wave bridges the pump and probe. Oscillation is achieved at 1.237 GHz, which matches the resonance of the acoustic mode, in a single-longitudinal-mode operation of the hybrid cavity. It has a high side mode suppression ratio of over 60 dB.
提出并演示了一种基于导波光在光子晶体光纤（PCF）中布里渊散射的光电子振荡器，该振荡器由 1μm 波段的光波激励。相对低的泵浦功率激励短长度的自制 PCF 导致泵浦波和探测波之间的强耦合。通过声波在泵浦和探测波之间架起桥梁的反馈环路实现了振荡器的工作。在混合腔的单纵模操作中，在声波共振处实现了 1.237GHz 的振荡器，其边模抑制比超过 60dB。
