Abstract

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 200nm-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 240νm outlet is estimated to be 7.5 × 107atomcm -2s-1 at a blue detuning of 1.2GHz. In order to increase the flux intensity to 1012atomcm-2s-1, we develop a Si-made funnel with a micron-sized outlet.
