摘　　要：介绍了光纤锥与回音壁光学微腔耦合得到系统传输谱线的理论,实验研究了光纤锥与香肠形微腔的传输谱线.实验中通过铬丝靠近微腔的方法来调节微腔的本征损耗.当铬丝沿着香肠腔的轴向移动时,传输谱线的变化说明香肠腔光学模式强度沿轴向会周期性的变化.论文的结果能增加人们对回音壁微腔的了解、促进其在光学传感等方面的应用.In this paper,the theory to obtain the transmission spectrum of the coupled fiber taper and whispering-gallery mode(WGM)optical microresonator is introduced firstly,and then the transmission spectrum of the fiber taper and the sausage-like microresonator(SLM)is experimentally studied.In our experiment,the intrinsic loss of the microresonator is adjusted by the way that a chrome tip is placed close to the microresonator.When the chromium tip moves along the axial direction of the SLM,the variety of the transmission spectrum shows that the optical mode intensity of the SLM changes periodically along the axial direction.The results of this paper can increase people’s understanding of the WGM microresonator and promote its application in optical sensing.
