  • blue detuned evanescent field surface traps for neutral atoms based on Mode Interference in ultrathin optical fibres
    New Journal of Physics, 2008
    Co-Authors: G Sague, A Baade, A Rauschenbeutel
    Abstract:

    We present and analyse a novel concept for blue-detuned evanescent field surface traps for cold neutral atoms based on two-Mode Interference in ultrathin optical fibres. When two or more transverse Modes with the same frequency co-propagate in the fibre, their different phase velocities cause a stationary Interference pattern to establish. Intensity minima of the evanescent field at any distance from the surface can be created and an array of optical microtraps can thus be obtained around the fibre. We discuss three possible combinations of the lowest order Modes, yielding traps at 100?200?nm from the fibre surface which, using a few tens of milliwatts of trapping laser power, have a depth of the order of 1?mK for caesium atoms and a trapping lifetime exceeding 100?s. The resulting trapping geometry is of particular interest because atoms in such microtrap arrays will be coupled to any additional field propagating in the fibre via the evanescent field, thereby realizing ensembles of fibre-coupled atoms.

Intensity minima of the evanescent field at any distance from the fibre surface can be created and an array of optical microtraps can thus be obtained in the evanescent field. We discuss three possible combinations of the lowest order Modes, yielding traps at one to two hundred nanometres from the fibre surface which, using a few ten milliwatts of trapping laser power, have a depth on the order of 1 mK for caesium atoms and a trapping lifetime exceeding 100 seconds. The resulting trapping geometry is of particular interest because atoms in such microtrap arrays will be coupled to any additional field propagating in the fibre via the evanescent field, thereby realising ensembles of fibre-coupled atoms.

  • quantum Interference and manipulation of entanglement in silicon wire waveguide quantum circuits
    New Journal of Physics, 2012
    Co-Authors: Damien Bonneau, C. M. Natarajan, M G Tanner, Erman Engin, N. Iizuka, N. Suzuki, Kazuya Ohira, Haruhiko Yoshida, Mizunori Ezaki, Robert Henry Hadfield
    Abstract:

    Integrated quantum photonic waveguide circuits are a promising approach to realizing future photonic quantum technologies. Here, we present an integrated photonic quantum technology platform utilizing the silicon-on- insulator material system, where quantum Interference and the manipulation of quantum states of light are demonstrated in components orders of magnitude smaller than previous implementations. Two-photon quantum Interference is presented in a multi-Mode Interference coupler, and the manipulation of entanglement is demonstrated in a Mach-Zehnder interferometer, opening the way to an all-silicon photonic quantum technology platform.
