Advanced noise reduction techniques for ultra-low phase noise optical-to-microwave division with femtosecond fiber combs
W. Zhang, Z. Xu, M. Lours +5
We report what we believe to be the lowest phase noise optical-to-microwave frequency division using fiber-based femtosecond optical frequency combs: a residual phase noise of -120…
Cascaded multiplexed optical link on a telecommunication network for frequency dissemination
Olivier Lopez, Adil Haboucha, Fabien Kéfélian +6
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 Int…
Stability measurements of microwave frequency synthesis with liquid helium cooled cryogenic sapphire oscillators
J. G. Hartnett, D. L. Creedon, D. Chambon +1
We report on the evaluation of microwave frequency synthesis using two cryogenic sapphire oscillators developed at the University of Western Australia. A down converter is used to…
Sub-100 attoseconds optics-to-microwave synchronization
W. Zhang, Z. Xu, M. Lours +4
We use two fiber-based femtosecond frequency combs and a low-noise carrier suppression phase detection system to characterize the optical to microwave synchronization achievable wi…
