Loaded microwave cavity for compact vapor-cell clocks
Michele Gozzelino, Salvatore Micalizio, Claudio E. Calosso +3
Vapor-cell devices based on microwave interrogation provide a stable frequency reference with a compact and robust setup. Further miniaturization must focus on optimizing the physi…
Reducing cavity-pulling shift in Ramsey-operated compact clocks
Michele Gozzelino, Salvatore Micalizio, Filippo Levi +2
We describe a method to stabilize the amplitude of the interrogating microwave field in compact atomic clocks working in a Ramsey approach. In this technique, we take advantage of…
Phase-shift in vapor cell and compact cold-atom frequency standards
Aldo Godone, Salvatore Micalizio
We report on a theoretical analysis of the phase-shift in compact atomic clocks working either with cold or thermal atoms. It is well known that in a microwave cavity with electrom…
Realization of a twin beam source based on four-wave mixing in Cesium
G. Adenier, D. Calonico, S. Micalizio +3
Four-wave mixing (4WM) is a known source of intense non-classical twin beams. It can be generated when an intense laser beam (the pump) and a weak laser beam (the seed) overlap in…
Evaluating Optical Fiber Links with Data Filtering and Allan Deviation
Claudio Eligio Calosso, Cecilia Clivati, Salvatore Micalizio
In this paper we propose a simple method to reject the high-frequency noise in the evaluation of statistical uncertainty of coherent optical fiber links. Specifically, we propose a…
Black Body Radiation Shift of the 133Cs Hyperfine Transition Frequency
S. Micalizio, A. Godone, D. Calonico +2
We report the theoretical evaluations of the static scalar polarizability of the 133Cs ground state and of the black body radiation shift induced on the transition frequency betwee…
