Abstract

Thermal properties and spectroscopic properties of the glass micro-sphere were presented in this paper. The Er³⁺ emission spectra of a kind of Erbium-doped glass microsphere were measured and discussed under 532nm excitation in a series of temperatures. The change in the temperature of the microsphere leads to a change in both the size and the index of refraction of the sphere, which results in the resonance shift of the peaks of whispering gallery modes in emission spectra. The temperature of the environment surrounding the sphere can be determined by monitoring the shift, which allows us to calibrate the sensing function of the shift proportional to temperature. Based on the thermal effects, we propose a novel optical temperature sensor using micrometer-sized sphere.
