Abstract
Sensing applications of dielectric microcavities with whispering gallery modes (WGMs) have been actively studied in the recent years. Here we investigated theoretically temperature microsensors based on different glasses, including common silica glass, as well as special germanate, tungsten-tellurite, arsenic sulfide and arsenic selenide glasses. We developed numerical model describing sensing characteristics of the considered microcavities. We found that the calculated temperature sensitivity does not depend on the microsensor size in the examined parameter range. The obtained temperature sensitivities for arsenic sulfide (42.2 pm/K near 1.55 $\mu$m) and arsenic selenide (48.1 pm/K near 1.55 $\mu$m) glass microcavities are several times larger than for common silica ones; it could facilitate the development of new precise microcavity-based sensors.
