提出了利用一种新型的光电振荡器（OEO）产生光频梳的方法，并着重研究了其自振荡特性。在OEO中，宽带LiNbO 3相位调制器由大幅度射频（RF）反馈信号驱动以产生深度相位调制的光波;相应地，通过自振荡产生带宽大于RF信号的光频梳。虽然它产生多频分量，但OEO表现出单模振荡器的特性。运行稳定，自启动。利用单频自激振荡技术成功地产生了带宽为120 GHz、频率间隔为9.95 GHz的光频梳。
Optical frequency comb generation by using a novel optoelectronic oscillator (OEO) is proposed and demonstrated with the emphasis placed on self-oscillating operation. In the OEO, a wideband LiNbO3 phase modulator is driven with a large-amplitude radio-frequency (RF) feedback signal to generate a deeply phase-modulated light wave; accordingly, an optical frequency comb with a bandwidth greater than the RF signal is generated by self-oscillation. Although it generates multifrequency components, the OEO exhibits characteristics of a single-mode oscillator. Its operation is stable and self-starting. An optical frequency comb with a 120 GHz bandwidth and 9.95 GHz frequency spacing was successfully generated by self-oscillation at a single frequency.
