Developing Microwave Photonic Temperature Sensors (1508.01433v1)
Published 6 Aug 2015 in physics.optics and physics.ins-det
Abstract: In recent years there has been considerable interest in exploiting the temperature dependence of sapphire whispering gallery mode frequency to develop a mechanically stable, high accuracy temperature sensor. Disk-resonator-based devices have been demonstrated to measure temperature with .01 K or better accuracy in the temperature range of 273 K to 373 K. Here we have utilized automated data acquisition and processing to rapidly evaluate a mechanically-stabilized sapphire whispering gallery mode resonator based on a hollow cylinder configuration.
