Cascaded optical fiber link using the Internet network for remote clocks comparison
Nicola Chiodo, Nicolas Quintin, Fabio Stefani +7
We report a cascaded optical link of 1100 km for ultra-stable frequency distribution over an Internet fiber network. The link is composed of four spans for which the propagation no…
Frequency and time transfer for metrology and beyond using telecommunication network fibres
Olivier Lopez, Fabien Kéfélian, Haifeng Jiang +11
The distribution and the comparison of an ultra-stable optical frequency and accurate time using optical fibres have been greatly improved in the last ten years. The frequency stab…
Tackling the Limits of Optical Fiber Links
Fabio Stefani, Olivier Lopez, Anthony Bercy +5
We theoretically and experimentally investigate relevant noise processes arising in optical fiber links, which fundamentally limit their relative stability. We derive the unsuppres…
Quantum cascade laser frequency stabilisation at the sub-Hz level
Bérengère Argence, Bruno Chanteau, Olivier Lopez +7
Quantum Cascade Lasers (QCL) are increasingly being used to probe the mid-infrared "molecular fingerprint" region. This prompted efforts towards improving their spectral performanc…
Two-Way Optical Frequency Comparisons Over 100km Telecommunication Network Fibers
Anthony Bercy, Fabio Stefani, Olivier Lopez +3
By using two-way frequency transfer, we demonstrate ultra-high resolution comparison of optical frequencies over a telecommunication fiber link of 100 km operating simultaneously d…
A widely tunable 10-m quantum cascade laser phase-locked to a state-of-the-art mid-infrared reference for precision molecular spectroscopy
Papa Lat Tabara Sow, Sinda Mejri, Sean K. Tokunaga +7
We report the coherent phase-locking of a quantum cascade laser (QCL) at 10-m to the secondary frequency standard of this spectral region, a CO2 laser stabilized on a saturated…
