  • 摘要: 频域稳定的高重频多波长光源是信道化和光通讯等领域的理想光源。为了满足高重频多梳齿激光源的应用需求,本文研制了49 GHz梳齿间隔的多波长激光源。通过优化I/Q两端射频信号和三个偏置点,IQ调制器稳定工作在载波抑制单边带模式,杂散频率成分抑制比达到27.5 dB。本文利用循环调制技术产生宽带多波长光频梳,并通过优化射频功率建立环内增益-损耗平衡,有效提升平坦度,获得了梳齿间隔为24.5 GHz、梳齿数目为28根、平坦度仅为3 dB、梳齿信噪比(TNR)达29 dB的多波长光频梳。在此基础 上,进一步利用法布罗(FP)滤波技术将频率间隔提升到49 GHz,最终得到梳齿数目达14根,平坦度为2.7 dB,TNR达19 dB,平均光功率为9 dBm的高重频多波长光频梳。由于采用了全保偏光纤器件和集成化技术,本系统具有一键式启动和长时稳定运行的特点,运行半小时的功率抖动标准差仅为0.5%,有望在各微波光子领域中应用。
