Abstract

Optical modes of a microbubble are studied both theoretically and experimentally. It is shown that the thermal red shift of the whispering gallery mode can be counteracted by selecting a suitable wall thickness and core material. Furthermore, the temperature sensitivity can be enhanced by selecting the appropriate wall thickness and core fluid such that a significant blue shift up to 30GHz/K is possible. Calculated shift rates are compared to preliminary results.
