We describe atom deflection with a slit-type deflector as an elemental technique of precise atom control using near-field light. In the demonstration experiments, cold Rb atoms deflected by repulsive near-field light induced in a 200?nm-wide slit are detected by means of two-step photoionization. Then, we consider a near-field-light lens of atomic de Broglie waves by developing the atom deflector. The feasibility of nanofocusing is shown by numerical analyses with Fourier atom optics. Finally, we describe atom funnels with evanescent light to generate a cold atomic beam required for atom manipulation using nanometric near-field light. The flux intensity of cold Rb atoms outputted from a 240??m outlet is estimated to be 7.5 ? 107?atom?cm?2?s?1 at a blue detuning of 1.2?GHz. In order to increase the flux intensity to 1012?atom?cm?2?s?1, we develop a Si-made funnel with a micron-sized outlet.

A slit-type atom deflector with near-field light

Kouki Totsuka, Haruhiko Ito, Kiichi Suzuki +3 more

We developed a near-field optical deflector for precise direction control of atomic motion using a dipole force. The blue-detuned, near-field light used to deflect atoms was generated near the edge of a 100-nm-wide slit and had a spatial distribution of 126 nm at a distance of 10 nm from the top edge. The deflection angle for a Rb atom was a function of light intensity, frequency detuning, and atomic velocity.
