Abstract

The frequency stability of lasers is limited by thermal noise in state-of-the-art frequency references. Further improvement requires operation at cryogenic temperature. In this context, we investigate a fiber-based ring resonator. Our system exhibits a first-order temperature-insensitive point around 3.55 K, much lower than that of crystalline silicon. The observed low sensitivity with respect to vibrations (<5 . 10(-11) m(-1) s(2)), temperature (-22(1) . 10(-9) K-2), and pressure changes (4.2(2) . 10(-11) mbar(-2)) makes our approach promising for future precision experiments.
