Ultra-sensitive thermometer based on a compact optical resonator

Research output: Contribution to journalEditorialOther

Abstract

This article demonstrates a thermometer based on millimeter-scale crystalline disk optical-resonator. By measuring the relative speed difference between 2 colors of light that travel inside the disk, the temperature changes of the disk was measured with a precision of 30 billionths of a degree.
