摘要： 作为光学微腔的一类，回音壁模式微瓶谐振腔可将光限制在极小三维区域振荡，具有高品质因子和低模式体积的特点。此外，其天然的中空通道可与微流控技术相结合，是实现光流传感器的重要平台。文章首先概述微瓶谐振腔的发展历程；然后简述微瓶谐振腔的传感机理，包括模式漂移、模式劈裂和模式展宽；接着对微瓶谐振腔理论模型和制备工艺进行介绍；随后着重阐述空心微瓶谐振腔的传感应用，包括温度传感、压力及超声波传感、生化传感、气体传感、磁场传感、液体属性传感、水凝胶相位传感等；最后对微瓶谐振腔的传感应用进行总结和展望。

Abstract: Whispering gallery mode microbottle resonator (MBR), as one type of optical microcavities, can confine light in a three-dimensional region, possessing the advantages of high quality factor and small mode volume. The inherently hollow channel of MBR can be combined with microfluidic technology, and thus become a versatile platform for optofluidic sensing. In this review, we start with a general overview of MBR development and then introduce the sensing mechanisms of MBR, which include mode shift, mode splitting and mode broaden. Subsequently, we describe the structure model and fabrication technology of MBR. Afterwards, we detail the sensing applications of hollow MBR, including temperature sensing, pressure and ultrasound sensing, bio-chemical sensing, gas sensing, magnetic field sensing, liquid properties sensing, and hydrogel phase sensing. In the end, we give a brief conclusion and envision of MBR sensing applications.
