Limitations due to residual interference in a fiber-based optical frequency reference at 1.55 $\mu$m

Autor: Manamanni, Karim, Steshchenko, Tatiana, Wiotte, Fabrice, Targat, Rodolphe Le, Abgrall, Michel, Lopez, Olivier, Cantin, Étienne, Pottie, Paul-Éric, Amy-Klein, Anne, Roncin, Vincent, Du-Burck, Frédéric

We present an experimental investigation of the stability limits specific to optical frequency standards using a fiber-optic architecture and semiconductor lasers. A compact setup composed of a semiconductor laser frequency-locked onto an acetylene t

Report

Searching for dark matter with an unequal delay interferometer

Autor: Savalle, Etienne, Hees, Aurelien, Frank, Florian, Cantin, Etienne, Pottie, Paul-Eric, Roberts, Benjamin M., Cros, Lucie, McAllister, Ben T., Wolf, Peter

Publikováno v: Phys. Rev. Lett. 126, 051301 (2021)

We propose a new type of experiment that compares the frequency of a clock (an ultra-stable optical cavity in this case) at time $t$ to its own frequency some time $t-T$ earlier, by "storing" the output signal (photons) in a fibre delay line. In ultr

On s'adapte! : une étude sur les stratégies utilisées pour faire face à l'insécurité alimentaire

Autor: Cantin, Étienne

L’insécurité alimentaire est un défi quotidien auquel doivent faire face environ 1,1 million de ménages canadiens (Statistique Canada, 2012). Les individus composant ces ménages doivent avoir recours à une diversité de stratégies visant à

Combining fiber Brillouin amplification with a repeater laser station for fiber-based optical frequency dissemination over 1400 km

Autor: Koke, Sebastian, Kuhl, Alexander, Waterholter, Thomas, Raupach, Sebastian M. F., Lopez, Olivier, Cantin, Etienne, Quintin, Nicolas, Amy-Klein, Anne, Pottie, Paul-Eric, Grosche, Gesine

Publikováno v: New J. Phys. 21 123017 (2019)

We investigate optical frequency dissemination over a 1400 km long fiber link in looped configuration over a pair of underground fibers between Braunschweig and Strasbourg. This fiber link is the first to combine fiber Brillouin amplifiers with a rep

Report

Two-Branch Fiber Link for International Clock Networks

Autor: Xu, Dan, Cantin, Etienne, Frank, Florian, Quintin, Nicolas, Meynadier, Frédéric, Tuckey, Philip, Amy-Klein, Anne, Lopez, Olivier, Pottie, Paul-Eric

Publikováno v: IEEE Transactions on Instrumentation and Measurement, Institute of Electrical and Electronics Engineers, 2019, 68 (6), pp.2195-2200

We present our work on realizing two-branch fiber links enabling multiple-partner clock comparisons in Europe. We report in detail on the setup connecting two long haul links, and report for the relative frequency stability and accuracy. We report on

Feedback control of coherent spin states using weak nondestructive measurements

Autor: Vanderbruggen, Thomas, Kohlhaas, Ralf, Bertoldi, Andrea, Cantin, Etienne, Landragin, Arnaud, Bouyer, Philippe

We consider the decoherence of a pseudo-spin ensemble under collective random rotations, and study, both theoretically and experimentally, how a nondestructive measurement combined with real-time feedback correction can protect the state against such
