Phase noise measurement of semiconductor optical amplifiers
Damien Teyssieux, Martin Callejo, Jacques Millo +2
We introduce a novel measurement method for the phase noise measurement of optical amplifiers, topologically similar to the Heterodyne Mach-Zehnder Interferometer but governed by d…
Short-term stability of a microcell optical reference based on Rb atom two-photon transition at 778 nm
Martin Callejo, Andrei Mursa, Rémy Vicarini +5
We report on the development and short-term stability characterization of an optical frequency reference based on the spectroscopy of the rubidium two-photon transition at 778 nm i…
Phase noise of a microwave photonic channel: direct-current versus external electro-optic modulation
Damien Teyssieux, Jacques Millo, Enrico Rubiola +1
We characterize the phase noise of a microwave photonic channel, where a 10 GHz signal is carried by an intensity-modulated light beam over a short optical fiber, and detected. Two…
Reduction of light shifts in Ramsey spectroscopy with a combined error signal
M. Shuker, J. W. Pollock, R. Boudot +4
Light-induced frequency shifts can be a key limiting contribution to the mid and long-term frequency instability in atomic clocks. In this letter, we demonstrate the experimental i…
Ramsey spectroscopy of high-contrast CPT resonances with push-pull optical pumping in Cs vapor
Xiaochi Liu, Jean-Marc Mérolla, Stéphane Guérandel +2
We report the detection of high-contrast and narrow Coherent Population Trapping (CPT) Ramsey fringes in a Cs vapor cell using a simple-architecture laser system. The latter allows…
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…
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…
Phase Noise in RF and Microwave Amplifiers
Rodolphe Boudot, Enrico Rubiola
Understanding the amplifier phase noise is a critical issue in numerous fields of engineering and physics, like oscillators, frequency synthesis, telecommunications, radars, spectr…
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…
