We have proposed a novel experiment to measure the interaction between an atom and a macroscopic surface at short distances based on the existing technology of optical lattice

We derive the unsuppressed delay noise for three configurations of optical links : two-way method, Sagnac interferometry, and actively compensated link, respectively designed

Optical fiber links have brought the potential to transfer frequency with much better accuracy and stability thanks to an active compensation of the phase noise

In this work we demonstrate for the first time that it is possible to transfer simultaneously an ultra-stable optical frequency and precise and accurate timing over 540 km using

The phase noise excursion is so large that we need to divide the tracked signal of the spans 3 and 4 (see Fig. In these conditions, signal-to-noise ratio is a critical parameter,
