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…
The Omega Counter, a Frequency Counter Based on the Linear Regression
E. Rubiola, M. Lenczner, P. -Y. Bourgeois +1
This article introduces the Ω counter, a frequency counter -- or a frequency-to-digital converter, in a different jargon -- based on the Linear Regression (LR) algorithm on time st…
Influence of the ESR saturation on the power sensitivity of cryogenic sapphire resonators
Vincent Giordano, Serge Grop, Pierre-Yves Bourgeois +2
Here, we study the paramagnetic ions behavior in presence of a strong microwave electromagnetic field sustained inside a cryogenic sapphire whispering gallery mode resonator. The h…
Controlling the Frequency-Temperature Sensitivity of a Cryogenic Sapphire Maser Frequency Standard by Manipulating Fe3+ Spins in the Sapphire Lattice
Karim Benmessai, Daniel L. Creedon, Mohamad Mrad +5
To create a stable signal from a cryogenic sapphire maser frequency standard, the frequency-temperature dependence of the supporting Whispering Gallery mode must be annulled. We re…
Unprecedented High Long Term Frequency Stability with a Macroscopic Resonator Oscillator
Serge Grop, Wolfgang Schäfer, Pierre-Yves Bourgeois +5
This article reports on the long-term frequency stabilty characterisation of a new type of cryogenic sapphire oscillator using an autonomous pulse-tube cryocooler as its cold sourc…
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…
