【摘要】：基于光通信系统对于全光调制和全光开关等的需求,从理论上和实验上研究了拉曼增益对回音壁模式光学微腔系统共振模式的全光调制。理论分析表明,拉曼增益能够补偿回音壁模式光学微腔系统的损耗,进而改变微腔系统的耦合机制,在不对微腔系统做任何机械性移动的前提下实现对系统共振透射率的连续调制。实验中采用光纤锥耦合的二氧化硅微芯圆环腔,利用560μW的低功率泵浦光引发的拉曼散射,波长为1 545.7 nm的信号光实现了13.5 d B的调制度,使得系统的耦合机制由欠耦合转化为临界耦合。
[Abstract]:Based on the demand of optical communication system for all-optical modulation and all-optical switch, the all-optical modulation of resonator mode of echo-mode optical microcavity system by Raman gain is studied theoretically and experimentally. Raman gain can compensate the loss of resonator mode optical microcavity system, and then change the coupling mechanism of microcavity system. The continuous modulation of the resonant transmittance of the microcavity system is realized without any mechanical movement of the microcavity system. In the experiment, the silicon dioxide microcore ring cavity coupled with fiber optic cone is used. By using the Raman scattering induced by the low power pump light of 560 渭 W, the modulation rate of 13.5 dB is realized by the signal light at 1 545.7 nm. The coupling mechanism of the system is transformed from undercoupling to critical coupling.
