Microbottle resonators (MBR) are bottle-like structures fabricated by varying the radius of an optical fiber. MBRs can support whispering gallery modes (WGM) by the total internal reflection of the light coupled into the MBRs. MBRs have a significant advantage in sensing and other advanced optical applications due to their light confinement abilities in a relatively small mode volume and having high Q factors. This review starts with an introduction to MBRs' optical properties, coupling methods, and sensing mechanisms. The sensing principle and sensing parameters of MBRs are discussed here as well. Then, practical MBRs fabrication methods and sensing applications are presented.
微瓶谐振器（MBR）是通过改变光纤半径制造的瓶状结构。MBR可以通过耦合到MBR中的光的全内反射来支持回音壁模式（WGM）。由于MBR在相对较小的模式体积中具有光限制能力且具有高Q因子，因此在传感和其他先进光学应用中具有显著优势。本文首先介绍了MBR的光学特性、耦合方法和传感机制。这里还讨论了MBR的传感原理和传感参数。然后，介绍了实际的MBR制造方法和传感应用。
