Abstract

Whispering gallery mode (WGM) resonators with high optical quality factor (Q) are sensitive to environment changes and are used in various sensing applications. We have developed a high-precision temperature sensor using a compactly packaged lithium niobate WGM resonator. This sensor offers a sensitivity of 34.38 pm °C⁻¹ and a high resolution of up to 5 .6 × 1 0 − 4 °C. It is portable with high Q, making it suitable for using outside the laboratory. The device is also resilient to changes in humidity, enhancing its practicality.
