摘　　要：微腔孤子光频梳在相干光通信、光学频率合成、激光雷达、微波光子学和量子光学等领域有着广阔的应用前景,高效棱镜耦合是晶体微腔孤子光频梳集成应用及系统封装的必然技术途径。文章研制开发了一种耦合效率和有载Q值分别达到71.56%和1.8×10^(9)的氟化镁微腔-棱镜耦合系统,并且基于该高效棱镜耦合系统实现了氟化镁微腔孤子光频梳和15.99 GHz低相噪微波信号产生,拍频信号相位噪声水平约为-117 dBc/Hz@10 kHz,极大推动了低相噪微型光电振荡器的实际应用发展。Soliton optical combs in microresonators have broad application prospects in coherent optical communication,optical frequency synthesis,lidar,microwave photonics and quantum optics.Efficient prism coupling provides an inevitable technical approach for integrated application and system packaging of soliton frequency combs in crystal microresonators.In this paper,a MgF2 microresonator-prism coupling system with the coupling efficiency of 71.56%and loaded Q value of 1.8×10^(9) was developed.Based on this efficient prism coupling system,the generation of MgF2 microresonator soliton frequency comb and the low-phase noise microwave signal of 15.99GHz were realized.And the phase noise level of beat frequency signal is about-117dB/[e-mail] will promote the practical application and development of low-phase noise micro-photoelectric oscillator.
