Testing Local Lorentz and Position Invariance and Variation of Fundamental Constants by searching the Derivative of the Comparison Frequency Between a Cryogenic Sapphire Oscillator and Hydrogen Maser
Michael Edmund Tobar, Peter Wolf, Sebastien Bize +2
The cryogenic sapphire oscillator (CSO) at the Paris Observatory has been continuously compared to various Hydrogen Masers since 2001. The early data sets were used to test Local L…
An agile laser with ultra-low frequency noise and high sweep linearity
Haifeng Jiang, Fabien Kefelian, Pierre Lemonde +2
We report on a fiber-stabilized agile laser with ultra-low frequency noise. The frequency noise power spectral density is comparable to that of an ultra-stable cavity stabilized la…
Ultra-Low Noise Microwave Extraction from Fiber-Based Optical Frequency Comb
J. Millo, R. Boudot, M. Lours +5
In this letter, we report on all-optical fiber approach to the generation of ultra-low noise microwave signals. We make use of two erbium fiber mode-locked lasers phase locked to a…
High-resolution optical frequency dissemination on a telecommunication network with data traffic
Fabien Kéfélian, Olivier Lopez, Haifeng Jiang +3
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…
Ultra low frequency noise laser by locking to an optical fiber delay line
Fabien Kéfélian, Haifeng Jiang, Pierre Lemonde +1
We report the frequency stabilization of an erbium-doped fiber distributed-feedback laser using an all-fiber based Michelson interferometer of large arm imbalance. The interferomet…
Ultra-low noise microwave generation with fiber-based optical frequency comb and application to atomic fountain clock
J. Millo, M. Abgrall, M. Lours +8
We demonstrate the use of a fiber-based femtosecond laser locked onto an ultra-stable optical cavity to generate a low-noise microwave reference signal. Comparison with both a liqu…
