Abstract
We present an ultrahigh-Q microrod resonator operated under ambient conditions that supports laser fractional frequency stabilization to the thermal-noise limit of 3 x 10−13 and a linewidth of 62 Hz. We characterize the technical-noise mechanisms for laser stabilization, which contribute significantly less than thermal noise. With all-fiber-integrated photonics, we generate optical and microwave reference signals provided by the microrod modes and the free- spectral range, respectively. Our results suggest the future physical considerations for a miniature, low noise, and robust optical-frequency source.Citation
