چکیده
The tapered SiO2 nanofiber for the trap [1] is drawn from a conventional optical fiber in a hydrogen-oxygen flame [2–4]. Fig. SM1 shows the radius r(z) as a function of axial coordinate z from SEM measurements for a set of 8 fiber tapers. The central region ∆z yields an average radius r(z) = 215 ± 10 nm for −3 < z < 3 mm, as shown in (b). The red curve is a theoretical calculation for r(z) [2] with the relevant taper pulling parameters and an effective heating length lH = 5.9 mm. Independent measurement gives lH = 6.1± 0.9 mm.

Demonstration of a state-insensitive, compensated nanofiber trap.
We report the experimental realization of an optical trap that localizes single Cs atoms ≃215 nm from the surface of a dielectric nanofiber. By operating at magic wavelengths for pairs of counterpropagating red- and blue-detuned trapping beams, differential scalar light shifts are eliminated, and vector shifts are suppressed by ≈250. We thereby measure an absorption linewidth Γ/2π=5.7±0.1 MHz...
متن کاملA state-insensitive, compensated nanofiber trap
Laser trapping and interfacing of laser-cooled atoms in an optical fiber network is an important tool for quantum information science. Following the pioneering work of Balykin et al (2004 Phys. Rev. A 70 011401) and Vetsch et al (2010 Phys. Rev. Lett. 104 203603), we propose a robust method for trapping single cesium atoms with a two-color state-insensitive evanescent wave around a dielectric n...
متن کاملCorrections to our results for optical nanofiber traps in Cesium
Several errors in Refs. [1, 2] are corrected related to the optical trapping potentials for a stateinsensitive, compensated nanofiber trap for the D2 transition of atomic Cesium. Section I corrects our basic formalism in Ref. [1] for calculating dipole-force potentials. Section II corrects erroneous values for a partial lifetime and a transition wavelength in Ref. [1]. Sections III and IV prese...

Title of thesis: TRANSMISSION SPECTRA OF RB ATOMS NEAR AN OPTICAL NANOFIBER. Burkley Delesdernier Patterson, Master of Science, 2016 Dissertation directed by: Professor Luis A. Orozco Department of Physics We present measurements of the transmission spectra of Rb atoms at 780 nm in the vicinity of a nanofiber. A uniform distribution of fixed atoms around a nanofiber should produce a spectrum th...
متن کاملCoherence properties of nanofiber-trapped cesium atoms.
We experimentally study the ground state coherence properties of cesium atoms in a nanofiber-based two-color dipole trap, localized ∼ 200 nm away from the fiber surface. Using microwave radiation to coherently drive the clock transition, we record Ramsey fringes as well as spin echo signals and infer a reversible dephasing time of T(2)(*) = 0.6 ms and an irreversible dephasing time of T(2)(') =...
