  • optical frequency transfer via 1840 km fiber link with superior stability
    International Frequency Control Symposium, 2014
    Co-Authors: Stefan Droste, Thomas Udem, G Grosche, Katharina Predehl, H Schnatz, T W Hansch, F Ozimek, Ronald Holzwarth
    Abstract:

    Optical frequency transfer over a 1840 km fiber link is presented. The link is actively stabilized to deliver a frequency with superior stability and accuracy. The Spectral Noise distribution of the stabilized link leads to an unprecedented fast averaging in the modified Allan deviation.

  • optical frequency transfer over a single span 1840 km fiber link
    Physical Review Letters, 2013
    Co-Authors: Stefan Droste, Thomas Udem, G Grosche, Katharina Predehl, H Schnatz, T W Hansch, F Ozimek, Ronald Holzwarth
    Abstract:

    : To compare the increasing number of optical frequency standards, highly stable optical signals have to be transferred over continental distances. We demonstrate optical-frequency transfer over a 1840-km underground optical fiber link using a single-span stabilization. The low inherent Noise introduced by the fiber allows us to reach short term instabilities expressed as the modified Allan deviation of 2×10(-15) for a gate time τ of 1 s reaching 4×10(-19) in just 100 s. We find no systematic offset between the sent and transferred frequencies within the statistical uncertainty of about 3×10(-19). The Spectral Noise distribution of our fiber link at low Fourier frequencies leads to a τ(-2) slope in the modified Allan deviation, which is also derived theoretically.

We demonstrate optical-frequency transfer over a 1840-km underground optical fiber link using a single-span stabilization. The low inherent Noise introduced by the fiber allows us to reach short term instabilities expressed as the modified Allan deviation of $2\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}15}$ for a gate time $\ensuremath{\tau}$ of 1 s reaching $4\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}19}$ in just 100 s. We find no systematic offset between the sent and transferred frequencies within the statistical uncertainty of about $3\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}19}$. The Spectral Noise distribution of our fiber link at low Fourier frequencies leads to a ${\ensuremath{\tau}}^{\ensuremath{-}2}$ slope in the modified Allan deviation, which is also derived theoretically.

    Co-Authors: Stefan Droste, Thomas Udem, Ronald Holzwarth, H Schnatz, T W Hansch, F Ozimek, S M F Raupach, G Grosche
    Abstract:

    We demonstrate optical frequency transfer over an 1840 km underground optical fiber link using a single-span stabilization. To compensate for more than 420 dB of optical attenuation of the light we use twenty Erbium doped fiber amplifiers along the entire link and two additional fiber Brillouin amplifiers. The good passive stability of our fiber link allows us to reach short term instabilities expressed as the modified Allan deviation of 3 × 10-15 for a gate time τ of 1 s reaching 4 × 10-19 in just 100 s. By comparing the sent and transferred frequencies we find no systematic offset within the statistical uncertainty of about 3 × 10-19. The Spectral Noise distribution of our fiber link at low Fourier frequencies leads to a τ-2 slope in the modified Allan deviation.
