Theory of thermal response characteristics of microbubble cavity coated with media is modeling by establishing a four-layer structure model
and thermal response characteristics of outer wall of microbubble cavity are discussed. Distribution of mode field and temperature sensitivity of media-coated microbubbles cavity is calculated numerically using finite element numerical simulation method. Computation results show that the microbubbles cavity with CaF

coated layer can effectively reduce the redshift effect caused by temperature increase in the first-order radial mode and the second-order radial modes
and in the third-order radial mode
its temperature sensitivity is about 55 % higher than that of the conventiona

microbubbles cavity. The research result has a great significance to further enhance sensing potential of microbubble cavity.
