Thermodynamically induced length fluctuations of high-reflectivity mirror coatings put a fundamental limit on sensitivity and stability of precision optical interferometers like gravitational-wave detectors and ultrastable lasers. The main contributi

Mechanical loss of dielectric mirror coatings sets fundamental limits for both gravitational wave detectors and cavity-stabilized optical local oscillators for atomic clocks. Two approaches are used to determine the mechanical loss: ringdown measurem

This Review covers optical clock networks that are established to synchronize remote optical clocks. Further upgrading of optical clock networks and their impact on a future redefinition of time are also discussed. Within the last decade, optical ato

We demonstrate a time scale based on a phase stable optical carrier that accumulates an estimated time error of $48\pm94$ ps over 34 days of operation. This all-optical time scale is formed with a cryogenic silicon cavity exhibiting improved long-ter

2018 IEEE International Frequency Control Symposium (IFCS).
We present the thermal noise limited performance of a cryogenic ultrastable silicon optical cavity operated at 4 K. A three-cornered comparison with two other ultrastable resonantors shows that the 4 K system is largely limited by a flicker frequency

Due to their orders-of-magnitude higher frequencies, optical frequency standards are beginning to outperform the best microwave standards with respect to their stability and accuracy and, hence, offer very promising prospects for novel space-based ap

The rapid increase in accuracy and stability of optical atomic clocks compared to the caesium atomic clock as the primary standard of time and frequency asks for a future redefinition of the second in the International System of Units (SI). The statu
