Digital Doppler-cancellation servo for ultra-stable optical frequency dissemination over fiber
Shambo Mukherjee, Jacques Millo, Baptiste Marechal +5
Progress made in optical references, including ultra-stable Fabry-Perot cavities, optical frequency combs and optical atomic clocks, have driven the need for ultra-stable optical f…
Ultra-compact reference ULE cavity
Alexandre Didier, Jacques Millo, Baptiste Marechal +7
We present a first experimental characterization of our ultra-compact, ultra-stable laser. The heart of the apparatus is an original Fabry-Perot cavity with a 25 mm length and a py…
Photonic Generation of High Power, Ultrastable Microwave Signals by Vernier Effect in a Femtosecond Laser Frequency Comb
Khaldoun Saleh, Jacques Millo, Baptiste Marechal +5
Optical frequency division of an ultrastable laser to the microwave frequency range by an optical frequency comb has allowed the generation of microwave signals with unprecedently…
Residual Phase Noise Measurement of Optical Second Harmonic Generation in PPLN Waveguides
Marion Delehaye, Jacques Millo, Pierre-Yves Bourgeois +6
We report on the characterization, including residual phase noise and fractional frequency instability, of fiber-coupled PPLN non-linear crystals. These components are devoted to f…
Frequency stability of a wavelength meter and applications to laser frequency stabilization
Khaldoun Saleh, Jacques Millo, Alexandre Didier +2
Interferometric wavelength meters have attained frequency resolutions down to the MHz range. In particular, Fizeau interferometers, which have no moving parts, are becoming a popul…
Characterization of the individual short-term frequency stability of Cryogenic Sapphire Oscillators at the 1e-16 level
Christophe Fluhr, Serge Grop, Benoît Dubois +3
We present the characterisation of three Cryogenic Sapphire Oscillators using the three-corner-hat method. Easily implemented with commercial components and instruments, this metho…
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…
ELISA: a cryocooled 10 GHz oscillator with 10-15 frequency stability
S. Grop, P. Y. Bourgeois, N. Bazin +8
This article reports the design, the breadboarding and the validation of an ultra-stable Cryogenic Sapphire Oscillator operated in an autonomous cryocooler. The objective of this p…
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…
Creating traveling waves from standing waves from the gyrotropic paramagnetic properties of Fe ions in a high-Q whispering gallery mode sapphire resonator
Karim Benmessai, Michael Edmund Tobar, Nicholas Bazin +3
We report observations of the gyrotropic change in magnetic susceptibility of the Fe electron paramagnetic resonance at 12.037GHz (between spin states and ) i…
Measurement of fundamental thermal noise limit in a cryogenic sapphire frequency standard using bimodal maser oscillations
Karim Benmessai, Daniel Lloyd Creedon, Michael Edmund Tobar +3
We report observations of the Schawlow-Townes noise limit in a cryogenic sapphire secondary frequency standard. The effect causes a fundamental limit to the frequency stability, an…
Maser Oscillation in a Whispering-Gallery-Mode Microwave Resonator
P. -Y. Bourgeois, N. Bazin, Y. Kersale +3
We report the first observation of above-threshold maser oscillation in a whispering-gallery(WG)-mode resonator, whose quasi-transverse-magnetic, 17th azimuthal-order WG mode, at a…
