Seismic monitoring using the telecom fiber network
Simone Donadello, Cecilia Clivati, Aladino Govoni +11
Laser interferometry enables to remotely measure microscopical length changes of deployed telecommunication cables originating from earthquakes. Long range and compatibility with d…
Embedded digital phase noise analyzer for optical frequency metrology
Simone Donadello, Elio K. Bertacco, Davide Calonico +1
Digital signal processing (DSP) is supporting novel in-field applications of optical interferometry, such as in laser ranging and distributed acoustic sensing. While the highest pe…
Beyond the fundamental noise limit in coherent optical fiber links
C. E. Calosso, E. Bertacco, D. Calonico +7
It is well known that temperature variations and acoustic noise affect ultrastable frequency dissemination along optical fiber. Active stabilization techniques are in general adopt…
Coherent optical frequency transfer at 5e-19 over a doubled 642 km fiber link
D. Calonico, E. K. Bertacco, C. E. Calosso +10
To significantly improve the frequency references used in radio-astronomy and precision measurements in atomic physics, we provide frequency dissemination through a 642 km coherent…
Frequency transfer via a two-way optical phase comparison on a multiplexed fiber network
Claudio Calosso, Elio K. Bertacco, Davide Calonico +6
We performed a two-way remote optical phase comparison on optical fiber. Two optical frequency signals were launched in opposite directions in an optical fiber and their phases wer…
