MAPAN, 2012
Latest progress in optical atomic clocks is so rapid that serious discussions toward the redefinition of the second is initiated. Besides single ion clocks developed since early 1980s, optical lattice clocks just invented a decade ago are one of strong candidates as a method to realize the revised definition.

The Idea of using cold atoms confined in an optical lattice for an optical clock was proposed in 2001 [1]. Since then, this idea became an experimental reality. We review here the contribution of LNE-SYRTE to these developments.

Optical coherence gratings and lattices
Optics Letters, 2014We introduce a class of partially coherent temporal/spatial sources, optical coherence gratings/lattices that have a Gaussian intensity profile and statistically stationary/homogeneous, periodic temporal/spatial coherence properties. We show that temporal coherence gratings generate partially coherent pulses with periodic spectra, whereas spatial ...

Polarization singularities in optical lattices
Optics Letters, 2004Polarization singularities are shown to be unavoidable features of three-dimensional optical lattices. These singularities take the form of lines of circular polarization, C lines, and lines of linear polarization, L lines. The polarization figures surrounding a C line (L line) rotate about the line with winding number +/-1/2 (+/-1).
