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…
In-line extraction of an ultra-stable frequency signal over an optical fiber link
Anthony Bercy, Saïda Guellati-Khélifa, Fabio Stefani +5
We demonstrate in-line extraction of an ultra-stable frequency signal over an optical link of 92-km of installed telecommunication fibers, following the proposition of G. Grosche i…
