The QTF-Backbone: Proposal for a Nationwide Optical Fibre Backbone in Germany for Quantum Technology and Time and Frequency Metrology
Tara Cubel Liebisch, Peter Kaufmann, Harald Schnatz +166
The recent breakthroughs in the distribution of quantum information and high-precision time and frequency (T&F) signals over long-haul optical fibre networks have transformative po…
Ultrastable lasers: investigations of crystalline mirrors and closed cycle cooling at 124 K
C. Y. Ma, J. Yu, T. Legero +8
We have investigated crystalline AlGaAs/GaAs optical coatings with three ultra-stable cavities operating at 4 K, 16 K, 124 K and 297 K. The response of the resonance frequencies of…
Substrate-transferred GaAs/AlGaAs crystalline coatings for gravitational-wave detectors: A review of the state of the art
G. D. Cole, S. Ballmer, G. Billingsley +16
In this Perspective we summarize the status of technological development for large-area and low-noise substrate-transferred GaAs/AlGaAs (AlGaAs) crystalline coatings for interferom…
Frequency stability of cryogenic silicon cavities with semiconductor crystalline coatings
Dhruv Kedar, Jialiang Yu, Eric Oelker +7
State-of-the-art optical oscillators employing cryogenic reference cavities are limited in performance by the Brownian thermal noise associated with the mechanical dissipation of t…
Excess noise and photo-induced effects in highly reflective crystalline mirror coatings
Jialiang Yu, Dhruv Kedar, Sebastian Häfner +9
Thermodynamically induced length fluctuations of high-reflectivity mirror coatings put a fundamental limit on sensitivity and stability of precision optical interferometers like gr…
A transportable clock laser system with an instability of
Sofia Herbers, Sebastian Häfner, Sören Dörscher +3
We present a transportable ultra-stable clock laser system based on a Fabry-Pérot cavity with crystalline AlGaAs/GaAs mirror coatings, fused silica (FS) mirror su…
