“…The interaction of atoms with a dielectric nanofiber has been studied theoretically in a number of papers Le Kien et al (2005bKien et al ( , 2006; Klimov and Ducloy (2004);Russell et al (2009); Minogin and Nic Chormaic (2010); Frawley et al (2012a). They demonstrate that the nanofiber modifies the boundary conditions and density of modes, affecting decay properties of the atom.…”

The development of optical nanofibers (ONF) and the study and control of their optical properties when coupling atoms to their electromagnetic modes has opened new possibilities for their use in quantum optics and quantum information science. These ONFs offer tight optical mode confinement (less than the wavelength of light) and diffraction-free propagation. The small cross section of the transverse field allows probing of linear and non-linear spectroscopic features of atoms with exquisitely low power. The cooperativity -the figure of merit in many quantum optics and quantum information systems -tends to be large even for a single atom in the mode of an ONF, as it is proportional to the ratio of the atomic cross section to the electromagnetic mode cross section. ONFs offer a natural bus for information and for inter-atomic coupling through the tightly-confined modes, which opens the possibility of one-dimensional many-body physics and interesting quantum interconnection applications. The presence of the ONF modifies the vacuum field, affecting the spontaneous emission rates of atoms in its vicinity. The high gradients in the radial intensity naturally provide the potential for trapping atoms around the ONF, allowing the creation of onedimensional arrays of atoms. The same radial gradient in the transverse direction of the field is responsible for the existence of a large longitudinal component that introduces the possibility of spin-orbit coupling of the light and the atom, enabling the exploration of chiral quantum optics.

“…Van der Waals interactions were manifested in the frequencydependent fluorescence power coupled from atom cloud into TNF. These interactions lead to a pronounced asymmetry in the lineshape of the coupled fluorescence spectrum 32 . It was observed that this asymmetry increased when the atom cloud around TNF was more compact and also when the radius of TNF was increased 32 .…”

“…These interactions lead to a pronounced asymmetry in the lineshape of the coupled fluorescence spectrum 32 . It was observed that this asymmetry increased when the atom cloud around TNF was more compact and also when the radius of TNF was increased 32 . Asymmetry occurs due to bound-bound transitions of the ground and excited state van der Waals potentials.…”

In this article we present some demonstrations of atom-photon interactions at low photon level using optical fibres. We report an experiment on the interaction between cold atoms produced in a magneto optical trap and tapered optical nanofibre and discuss some applications of the same. We then expound our experimental plan to study nonlinear processes such as electromagnetically induced transparency in laser cooled atomic medium confined within a hollow core photonic crystal fibre. Possible applications of this system are also discussed.

“…The ground-state cesium atom has its dominant (D 2 ) line at 852 nm, which gives a van der Waals constant of C 3 = 2π × 1.56 kHz μm 3 [23], and this value will be used throughout this paper. In the following we will also use the simplified expression (14) whenever justified while making sure the full expression gives identical results.…”

Original citationHennessy, T. and Busch, T. (2012) We describe theoretically a setup in which a tapered optical nanofiber is introduced into an optical lattice potential for cold atoms. First, we consider the disturbance to the geometry of the lattice potential due to scattering of the lattice lasers from the dielectric fiber surface and show that the resulting distortion to the lattice can be minimized by placing the fiber at an appropriate position in the lattice. We then calculate the modifications of the local potentials that are achievable by transmitting off-resonant light through the fiber. The availability of such a technique holds the potential to deterministically create and address small well-defined samples of atoms in the evanescent field of the tapered nanofiber.
