High-Q photonic device for trapping and detecting a single atom on a chip

Abstract

Recent progress in manufacturing high-Q dielectric microresonant structures may enable their use as photonic devices that can manipulate and/or detect single atoms on a nanometer scale. Of specific interest is the wafer-based manufacturing of resonators where good control of the physical characteristics can be achieved during fabrication and operation when integrated with other functions on the chip. We show that this "all-optical" trapping should be stable. We discuss atom detection efficiencies and the feasibility for non-destructive measurements in such systems and their dependence on key parameters such as atom distance from the surface, intensity of red- and blue-detuned laser pump fields, and disk size.

Recent progress in the manufacturing of high Q dielectric microresonant structures enables their use as photonic devices that can manipulate and/or detect single atoms on a nanometer scale. Of specific interest is the wafer-based manufacturing of resonators where a good control of the physical characteristics can be achieved during fabrication and during operation, while at the same time allowing integration with other functions on the chip. We also discuss experimental feasibility and compare with first experiments in the field.

Simultaneous optical trapping and detection of atoms by microdisk resonators

Michael Rosenblit, Yonathan Japha, Péter Horák +1 more

We propose a scheme for simultaneously trapping and detecting single atoms near the surface of a substrate using whispering gallery modes of a microdisk resonator. For efficient atom-mode coupling, the atom should be placed within approximately $150\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ from the disk. We show that a combination of red and blue detuned modes can form an optical trap at such distances while the backaction of the atom on the field modes can simultaneously be used for atom detection. We investigate these trapping potentials including van-der-Waals and Casimir-Polder forces and discuss corresponding atom detection efficiencies, depending on a variety of system parameters. Finally, we analyze the feasibility of nondestructive detection.

Design of a trapping potential for detecting single atoms by a microdisk resonator on a chip

Michael Rosenblit, Yonathan Japha, Péter Horák +1 more

We investigate simultaneous optical trapping and optical detection of a single Rb atom near the surface of a toroidal microdisk. Light is coupled into two high-Q whispering-gallery modes of the disk which provide attractive and repulsive potentials, respectively, via their evanescent fields. The sum potential including van-der-Waals and Casimir-Polder surface forces exhibits a minimum at distances of the order of 100 nm from the disk surface. The back-action of an atom held in this trap on the light fields is sufficiently strong to provide a measurable effect. We discuss atom trapping and detection properties in dependence on a variety of system parameters.

Tailored-waveguide based photonic chip for manipulating an array of single neutral atoms

Ke Min, Feng Zhou, Xiao Li +2 more

We propose a tailored-waveguide based photonic chip with the functions of trapping, coherently manipulating, detecting and individually addressing an array of single neutral atoms. Such photonic chip consists of an array of independent functional units spaced by a few micrometers, each of which is comprised of one silica-on-silicon optical waveguide and one phase Fresnel microlens etched in the middle of the output interface of the optical waveguide. We fabricated a number of photonic chips with 7 functional units and measured optical characteristics of these chips. We further propose feasible schemes to realize the functions of such photonic chip. The photonic chip is stable, scalable and can be combined with other integrated devices, such as atom chips, and can be used in the future hybrid quantum system and photonic quantum devices.

PROGRESS IN ATOM CHIPS AND THE INTEGRATION OF OPTICAL MICROCAVITIES

E. A. HINDS, M. TRUPKE, Benoît Darquié +2 more

We review recent progress at the Centre for Cold Matter in developing atom chips. An important advantage of miniaturizing atom traps on a chip is the possibility of obtaining very tight trapping structures with the capability of manipulating atoms on the micron length scale. We recall some of the pros and cons of bringing atoms close to the chip surface, as is required in order to make small static structures, and we discuss the relative merits of metallic, dielectric and superconducting chip surfaces. We point out that the addition of integrated optical devices on the chip can enhance its capability through single atom detection and controlled photon production. Finally, we review the status of integrated microcavities that have recently been demonstrated at our Centre and discuss their prospects for future development.
