It has been previously demonstrated that the optical whispering-gallery modes inside a micro-sphere resonators can be used for extremely sensitive temperature sensing. This work attempts to utilize the high-resolution measurements of an optical micro-annulus in order to detect the temperature change in a current carrying wire. A wire is coated with a thin layer of dielectric material as an annular sensor and positioned next to an optical taper. Current is then run through the wire to create joule heating and the temperature change is correlated with the frequency shift in the whispering-gallery mode resonance inside the micro-annulus. The experimental results will be analyzed and presented.

A fiber optic whispering gallery mode (WGM) resonator was proposed and realized by integrating an inline polymer waveguide with a microsphere mounted on it. The polymer waveguide with a diameter of 1 μm was printed with femtosecond laser-assisted multiphoton polymerization in a section of a grooved hollow-core fiber, which was sandwiched between two single-mode fibers. Two WGW resonators assembled with microspheres of different sizes were prepared. The transmission spectra of those stimulated WGMs were investigated both in simulation and experimentally. The temperature response of the resonators was particularly studied, and a linear sensitivity of −593 pm/°C was achieved from 20 °C to 100 °C.
