Abstract : This thesis presents the confinement of cold atoms in dipolar traps formed by Fresnel microstructures fabricated on the surface of a metallic mirror. The thesis consists of two parts.
In the first part we undertake a detailed description of the experimental setup realized for a mirror-magneto-optic trap (MMOT) and discuss the characteristics of this trap.
In the second part we discuss the theoretical, numerical and experimental tools that we have used for the design and characterization of various Fresnel microlens types. We then study the loading, temperature and lifetime of cesium atoms captured into dipole traps formed from these microstructured Fresnel lenses. Several different geometries are presented: simple lenses (cylindrical and circular), variable-focus lenses and lens arrays. Dynamical addressing of each member of the lens array is demonstrated. Perspectives for future development are finally discussed, in particular concerning the variable-focus lenses and the possibility of magnetic-field addressing of each member of a lens array.
