Accurate laser frequency locking to optical frequency combs under low-signal-to-noise-ratio conditions
C. Guo, M. Favier, N. Galland +7
We demonstrate a method for accurately locking the frequency of a continuous-wave laser to an optical frequency comb in conditions where the signal-to-noise ratio is low, too low t…
Phase noise characterization of sub-hertz linewidth lasers via digital cross correlation
Xiaopeng Xie, Romain Bouchand, Daniele Nicolodi +3
Phase noise or frequency noise is a key metrics to evaluate the short term stability of a laser. This property is of a great interest for the applications but delicate to character…
Photonic microwave signals with zeptosecond level absolute timing noise
Xiaopeng Xie, Romain Bouchand, Daniele Nicolodi +11
Photonic synthesis of radiofrequency revived the quest for unrivalled microwave purity by its seducing ability to convey the benefits of the optics to the microwave world. In this…
Characterizing a fiber-based frequency comb with electro-optic modulator
W. Zhang, M. Lours, M. Fischer +3
We report on the characterization of a commercial-core fiber-based frequency comb equipped with an intracavity electro-optic modulator (EOM). We investigate the relationship betwee…
Amplitude to phase conversion of InGaAs pin photo-diodes for femtosecond lasers microwave signal generation
W. Zhang, T. Li, M. Lours +3
When a photo-diode is illuminated by a pulse train from a femtosecond laser, it generates microwaves components at the harmonics of the repetition rate within its bandwidth. The ph…
High-resolution microwave frequency dissemination on an 86-km urban optical link
O. Lopez, A. Amy-Klein, M. Lours +2
We report the first demonstration of a long-distance ultra stable frequency dissemination in the microwave range. A 9.15 GHz signal is transferred through a 86-km urban optical lin…
