“…Thus, with lower probe powers and suitable detectors, it is possible to retrieve lineshapes which are almost free from power broadening. One would expect to observe inhomogeneous broadening on the red side of the absorbance spectrum [14], [17], [19]. In our system, the evanescent coupling region extends from the nanofibre surface radially outwards to a 1/e distance of about 400 nm.…”

The nanofiber is a submicron-diameter cylindrical waveguide fabricated from commercially-available optical fiber using a heat-and-pull rig. The nanofiber can be used as a 'dark' or 'bright' probe depending on whether laser light is coupled into the nanofiber. We demonstrate the use of an optical nanofiber as an absorption spectroscopy tool for cold atoms. A frequency-scanned probe beam is launched through the nanofiber and the resonant light is absorbed at the waist of the nanofiber by nearby cold 85 Rb atoms. We present recent singlephoton absorption results and comment on the role of surface interactions. Future work on 2photon absorption using excited state electronic transitions in 85 Rb is discussed.

“…There have been a number of theoretical [12][13][14] and experimental [15], [16] studies on the coupling of the resonance fluorescence from laser-cooled atoms into the guided modes of optical nanofibers. The resonance fluorescence has contributions from elastic scattering and inelastic scattering components.…”

“…Because of their large evanescent field (Sect. 3.1) OMs can have an extraordinary high collection efficiency of the luminescent light emitted by atoms in their proximity and have been used for detecting , manipulating and probing atomic fluorescence . Interestingly, the fraction of power emitted into the OM guided mode increases for a larger number of atoms and can approach unity for large ensembles.…”

“…1, as the fiber is tapered down this geometry adiabatically transforms to a step-index waveguide in which the light is entirely guided with air (or vacuum) as the cladding ("cladding-air" guidance), having an index difference close to 0.5. Detailed vector-mode solutions are required for such "strongly guiding" waveguides, and are described in a number of treatments Marcuse (1981) ;Snyder and Love (1983); Yariv (1990); Marcuse (1991); Sagué (2008); , while in the weakly guiding limit, a scalar treatment is sufficient. Here we present a summary of the vector-mode solutions from Hoffman (2014), and discuss some of the relevant aspects of optical nanofibers.…”

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.
