Precise control of atoms with optical near fields: deflection and trap

Haruhiko Ito, Akifumi Takamizawa, H. Tanioka +1 more

We present a new scheme of atom manipulation by means of a sharpened optical fiber with near-field light. In particular, we discuss the feasibility of deflecting and trapping Rb atoms. The optical potential produced by the dipole force is estimated from numerical calculations based on the Yukawa-type intensity distribution. We show that a slow Rb atom can be deflected at a large deflection angle. A static atom trap can be made near the tip of a sharpened fiber. A cold Rb atom is captured at the minimum of the trap potential composed of the repulsive optical potential and the attractive van der Waals potential. A spatial intensity distribution of an optical near-field produced near the tip of a protrusion-type fiber is measured in the fiber-to-probe configuration with a shear-force technique. We also describe an atom funnel to form a cold atomic beam required for the near-field light manipulation.

Near-field optical guidance and manipulation of atoms

Haruhiko Ito, Kouhei Otake, Motoichi Ohtsu

We describe guiding of neutral atoms through a hollow optical fiber with a micron-sized hollow core. Two-step photoionization experiment shows the frequency dispersion properties of the dipole interaction between an atom and an optical near field. These characteristics are advantageous to species- and state-selective manipulation of atoms. Then we discus a new scheme of atom deposition by means of the guiding technique, including a numerical simulation. We also present two methods for controlling atomic motion using a sharped optical fiber with a nanometric optical n ear field, i.e., atom deflection and atom trap. Deflection angle and trap potential are estimated based on a near-field intensity distribution derived from a Yukawa-type screened potential. The manipulation techniques are useful for precise control of atoms with a spatial accuracy beyond diffraction limit, which will lead to atomic-scale crystal growth.
