The understanding and multiple experimental demonstrations of atom interferometry have allowed the design and realisation of cold atom inertial sensors. These devices, initially intended for metrology and high-precision measurements, are now in the industrialization phase and constitute one of the pillars of the second quantum revolution. The first sensors were designed to operate in laboratories, and as such they are hardly suitable for field applications such as inertial navigation. The central objective of this thesis was therefore to study capacitance technologies for the realisation of compact inertial sensors. An atom chip was chosen as the key element of the physical package. It allows to reduce the size of sensors while giving the possibility to have a cold or ultra-cold coherent source of atoms and the realisation of different functions necessary for atomic interferometry. First, the manuscript discusses the cooling and preparation of atoms in a magnetic trap. . Secondly it presents the implementation of different laser beam based atomic optics elements, as well as the development of a given protocol for inertial rotation measurement with a linear magnetic guide. In particular, the experimental study of the coherent propagation of atoms in this guide is reported.

An essential factor in inertial navigation applications is the stability of inertial measurement units. This parameter is seriously affected by the dead time between measurements. As cold atom sensors have a significant dead time, due to the cooling process, the search for a possible solution to this problem was a subject of this work. Specifically, a new technique was implemented for the microwave and non-destructive measurement of the population of atomic levels used in an interferometer. This detection method leads to a significant reduction of the dead time over several interferometric measurement cycles, with a strong potential for integration on atom chips.

A study has been done on the double modulation coherent population trapping atomic clock and its stability limitations over long times. An overview of the state of the art of compact clocks in the world has been given. The theoretical framework of the DM-CPT is then presented, followed by a description of the experimental set-up with the laser source, the microwave synthesis and the atomic resonator. A detailed account of the limitations of the clock has been given at 1 s and 1000 s by listing the different contributions. Finally, a new time sequence has been proposed to correct the light effects due to the imbalances between the two wavelengths used for the CPT by acting on the microwave power, thus improving the stability on long times. In conclusion, the DM-CPT clock is positioned in relation to other available technologies and some further improvements to be made have been proposed.

This PhD thesis presents the latest advances in SYRTE operational frequency chain, based on ultrastable oscillators at different wavelengths and frequency comb technologies. After describing this metrological architecture, the work focuses on the noise analysis of its critical elements so as to determine its stability and accuracy limits. The performance of these capabilities was measured by performing simultaneous comparisons of oscillators pairs with 3 fully independent chains. The relative resolutions obtained, below 1×10^–16 in the microwave and 1×10^–18 in the optical domains, demonstrate that these means of measurement are not a limiting factor, even with state-of-the-art clocks. A key element of optical clocks is the light probing the narrow atomic transition. While in practice ultrahigh stability lasers are built in the infrared range, the technique known as transfer of spectral purity makes use of a frequency comb to transmit its level of performance to target visible wavelengths (698 nm and 1 062 nm in the SYRTE case). This work demonstrates an out-of-loop transfer reaching a resolution better than 5×10^–18 at 1 s. This lead to the first synchronized interrogation between the SYRTE strontium and mercury clocks when their respective clock lasers benefit from the transfer of a single master at 1 542 nm, resulting in a 2-fold improvement of their stability ratio measurement.

This thesis presents two research projects that are placed in the context of the two main theories of modern physics: general relativity and the standard model. — The first project aims at measuring the gravitational redshift between the PHARAO clock of the ACES-PHARAO payload (which will be docked on the ISS) and the best clocks of the different metrology laboratories. As a data processing and analysis center, the SYRTE laboratory is actively preparing the future launch of the mission by developing various dedicated software. This manuscript presents the last stage of processing which allowed to validate the expectations of the mission and which will allow to extract the violation parameter of Albert Einstein’s theory. — The second project is a dark matter research experiment located at Paris Observatory. According to the ultra-light scalar field theory, the dark matter surrounding the Earth would be at the origin of a variation of the fundamental constants of Nature. This causes a temporal oscillation of the length of the ultrastable cavity and of the optical fiber composing the Mach-Zehnder interferometer of the experiment. The development and optimization of the optical device allowed to reach a level of sensitivity low enough to place competitive constraints on the dark matter models but unfortunately did not reveal any trace of this unknown matter in the sensitivity zone of the experiment.

This thesis describes the frequency stabilization of a 1.54 µm fiber laser on an iodine hyperfine line at 514 nm, after a frequency tripling process. An important part of this work is dedicated to the frequency tripling process (ω to 3ω), and to the development of an original approach of a phase modulation operated in the IR, while the Doppler free spectroscopy is operated at 1.54 µm. To do this, a phase modulation by an EOM, a power stabilization action by an AOM and two periodically polled wave guided Lithium Niobate nonlinear crystals are used. A harmonic power higher than 100 mW at 514 nm) is generated using a fundamental optical power less than 1 W at 1.54 µm. The optical setup is fully fibered. The total power consumption of this frequency tripling process is 20 W only. Using a specific operation mode, this laser setup emits simultaneously three frequency-stabilized and intense radiations at 1.54 µm, 772 nm and 514 nm. Following this development, a very compact laser spectroscopy setup was built, based on a short sealed quartz cell, which contains the molecular iodine vapor. An optical power lower than 10 mW in the green is sufficient to carry out the iodine vapor interrogation, and to detect the hyperfine saturation transitions, with a high quality factor around 514 nm (Q higher than 2×10⁹). A frequency stability at the level of 3×10^-14 τ^-1/2 with a minimum value of 4×10^-15 at 200 s is demonstrated using a phase modulation operated in the green. When the phase modulation is applied in the IR, a relative frequency stability at the level of 5×10^-14 τ^-1/2 was obtained. This work has allowed to identify the major key components, in order to develop in the near future, a fully fibered and compact stabilized laser prototype occupying a total optical volume less than 10 litres. We have pointed out an important limitation to the mid-term frequency stability due to the Zeeman Effect as 10^-15/mGauss. Such frequency stabilized laser source could be used in numerous space projects that require ultra-stable frequency optical links, inter-satellite or ground to space, for space geodesy (GRICE), Earth gravitational field measurement (GRACE-FO, NGGM), gravitational waves detection (LISA), etc.
