An atom chip interferometer
B. Wirtschafter, C. I. Westbrook, M. Dupont-Nivet
We have realized an interferometer using a thermal cloud of magnetically trapped rubidium 87 atoms on a chip. The interferometer resembles a Ramsey interferometer with a state sele…
Silicon nitride based integrated photonic circuit to control a cold-atom source
H. Snijders, S. Hello, B. Wirtschafter +7
We have developed a silicon nitride based photonic integrated circuit (PIC) that is responsible for the cooling, pumping and imaging of cold rubidium 87 atoms. The photonic integra…
Noise budget of a trapped on chip cold atom Rubidium 87 clock
M. Dupont-Nivet, B. Wirtschafter, S. Hello +1
In this paper, we present a realisation of an on chip atomic clock using a cold cloud of Rubidium 87 atoms. This clock is based on a Ramsey interferometer with a Ramsey time around…
Miniaturized optical system for a chip based cold atom inertial sensor
S. Hello, H. Snijders, B. Wirtschafter +6
We miniaturized the complex optical system responsible for the cooling, pumping and imaging of an on-chip based cold atom inertial sensor. This optical bench uses bonded miniature…
