An optical drill is proposed for the nanofabrication of three-dimensional (3D) (diamond-like) lattices in positive photoresists, thereby opening a way towards 3D photonic crystals at optical wavelengths. Basically, an ensemble of coherent light beams

The dynamics of atoms in an antidot optical lattice is investigated both through numerical simulations and experiments performed with cesium atoms. The calculated atomic trajectories display pinball-like bounces on the antidots. These bounces manifes

We report the observation of resonances in the intensity correlation spectra of a 3D rubidium optical lattice, which we attribute to light scattering from propagating atomic density fluctuations in the lattice. This process is the spontaneous analog

All the bright optical lattices studied so far have been designed to obtain a circularly polarized light at the bottom of the optical potential wells. This condition minimizes the departure rate of the atoms from the fundamental adiabatic surface and

We present an experimental investigation of a three-dimensional (3D) optical lattice where the light polarization is linear at the bottom of the potential wells instead of being circular as in previous studies. In the present situation, optical pumpi

We present a study of pump-probe spectroscopy experiments in an optical lattice. The probe transmission spectrum contains three types of resonances similar to those found in usual nonlinear media: Raman, Brillouin and Rayleigh resonances. We show evi

We present an experimental investigation of the local dynamics and spatial diffusion of atoms in a rubidium optical lattice using polarization-selective intensity correlation spectroscopy in both the time and frequency domains. Autocorrelations of th

We show how the internal dynamics of a multilevel atom are modified in the vicinity of the interface between a vacuum and a simple or multilayered lossless dielectric medium. Optical Bloch equations are derived, which take into account the modificati

We present a new type of lattice for trapping cold atoms in nearly-dark states where they weakly interact with light. The periodic potential is obtained with fields in a lin ⊥ lin configuration tuned on the blue side of a J → J transition and in

We present a method for creating three-dimensional optical lattices starting from well-known one-dimensional configurations. This method is applied to the case of the lin ⊥ lin molasses and gives rise to optical potentials having orthorhombic symme
