two way optical frequency comparisons at 5 10 21 relative stability over 100 km Telecommunication Network fibers
Physical Review A, 2014Co-Authors: Anthony Bercy, Olivier Lopez, Fabio Stefani, Christian Chardonnet, Pauleric Pottie, Anne AmykleinAbstract: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 digital data transfer. We first propose and experiment a bi-directional scheme using a single fiber. We show that the relative stability at 1 s integration time is 7 10^18 and scales down to 5 10^21. The same level of performance is reached when an optical link is implemented with an active compensation of the fiber noise. We also implement a real-time two-way frequency comparison over a uni-directional Telecommunication Network using a pair of parallel fibers. The relative frequency stability is 10^15 at 1 s integration time and reaches 2 10^17 at 40 000 s. The fractional uncertainty of the frequency comparisons was evaluated for the best case to 2 10^20. These results open the way to accurate and high resolution frequency comparison of optical clocks over intercontinental fiber Networks.

cascaded multiplexed optical link on a Telecommunication Network for frequency dissemination
arXiv: Quantum Physics, 2010Co-Authors: Olivier Lopez, Christian Chardonnet, Anne Amyklein, A Haboucha, Fabien Kefelian, Haifeng Jiang, B Chanteau, Vincent Roncin, Georgio SantarelliAbstract:We demonstrate a cascaded optical link for ultrastable frequency dissemination comprised of two compensated links of 150 km and a repeater station. Each link includes 114 km of Internet fiber simultaneously carrying data traffic through a dense wavelength division multiplexing technology, and passes through two routing centers of the Telecommunication Network. The optical reference signal is inserted in and extracted from the communication Network using bidirectional optical add-drop multiplexers. The repeater station operates autonomously ensuring noise compensation on the two links and the ultra-stable signal optical regeneration. The compensated link shows a fractional frequency instability of 3 \times 10-15 at one second measurement time and 5 \times 10-20 at 20 hours. This work paves the way to a wide dissemination of ultra-stable optical clock signals between distant laboratories via the Internet Network.

High-resolution optical frequency dissemination on a Telecommunication Network with data traffic
Optics Letters, 2009Co-Authors: Fabien Kefelian, Olivier Lopez, Christian Chardonnet, Haifeng Jiang, Anne Amy-klein, Georgio SantarelliAbstract:We transferred the frequency of an ultra-stable laser over a 108 km urban fiber link comprising 22 km of optical communications Network fiber simultaneously carrying Internet data traffic. The metrological signal and the digital data signal are transferred on two different frequency channels in a dense wavelength division multiplexing scheme. The metrological signal is inserted into and extracted from the communications Network by using bidirectional off-the-shelf optical add-drop multiplexers. The link-induced phase noise is measured and cancelled with round-trip technique using an all-fiber-based interferometer. The compensated link shows an Allan deviation of a few 10-16 at one second and below 10-19 at 10,000 seconds. This opens the way to a wide dissemination of ultra stable optical clock signals between distant laboratories via the Internet Network.
