Design and Modeling of Biological Liquid Temperature Sensor Based on Fiber-Coupled MicrodiskWhispering Gallery Modes

In this work we designed a blood serum temperature sensor based on fiber-coupled microdisk. The shift of resonance frequencies or frequencies of whispering gallery modes was used to detect the temperature in the range of 15 to 35 0 C. Although the thermal dispersion or dn/dT effect of liquids for a small change of temperature is low, however due to high quality factor of microdisks, these changes become detectable. Our theoretical results show a slop of 2MHz/0C for frequency shift versus temperature change. The design is applicable for every liquid warming up in which its thermal data are in hand.
