Microfluidic sorting in an optical lattice
Nature, 2003The response of a microscopic dielectric object to an applied light field can profoundly affect its kinetic motion. A classic example of this is an optical trap, which can hold a particle in a tightly focused light beam. Optical fields can also be used to arrange, guide or deflect particles in appropriate light-field geometries.

We study a new type of optical lattice in which the localized atoms experience a much reduced optical pumping and fluorescence rate. An optical standing wave is tuned to the blue of the F = 2 ? F = 2 transition of the (87)Rb D(2) line and induces periodic optical potentials by coupling the F = 2 ground state to both the F = 2 and F = 3 excited states ...

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 ...

Engineering novel optical lattices
Reports on Progress in Physics, 2013Optical lattices have developed into a widely used and highly recognized tool to study many-body quantum physics with special relevance for solid state type systems. One of the most prominent reasons for this success is the high degree of tunability in the experimental setups.

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).
