Spectral distribution of atomic fluorescence coupled into an optical nanofibre

Journal of Physics B: Atomic, Molecular and Optical Physics, 2009
We analyse the lineshape of the fluorescence emitted by a cloud of optically excited cold atoms and coupled into an optical nanofibre. We examine the efficiency of the fluorescence coupling and describe the asymmetry of the lineshape caused by the redshifts arising from both the van der Waals and Casimir–Polder interaction of the atoms with the surface

Optical Properties of Cellulose Nanofibre Films at High Temperatures [PDF]

Journal of Polymer Research, 2022
AbstractNanocelluloses and their different designs, such as films and nanopapers, have gained considerable interest in many application areas due to their unique properties. For many purposes, such as packaging and electronics, the thermal stability and optical properties of nanocellulose materials are crucial characteristics.

Stable low-loss optical nanofibres embedded in hydrophobic aerogel [PDF]

Optics Express, 2011
Nanofibres, optical fibres narrower than the wavelength of light, degrade in hours on exposure to air. We show that encapsulation in hydrophobic silica aerogel (refractive index 1.05) provides protection and stability (over 2 months) without sacrificing low attenuation, strong confinement and accessible evanescent field. The measured attenuation was

Polarization response and scaling law of chirality for a nanofibre optical interface [PDF]

Scientific Reports, 2017
AbstractTwo port optical devices couple light to either port dependent on the input photon state. An important class of two-port devices is that of evanescently-coupled interfaces where chirality of photon coupling can lead to important technological applications.

Magnetically trapped atoms in the vicinity of an optical nanofibre [PDF]

Applied Physics B, 2020
AbstractMagnetically trapped $$^{87}$$87Rb atoms have been observed near a single-mode optical nanofibre. Approximately $$1\times 10^6$$1×106 atoms were optically pumped to the $${|{F=2,m_\mathrm{F}=2}\rangle }$$|F=2,mF=2⟩ state and held in the trap with a trap lifetime of up to 2 s.

Hybrid System of an Optical Nanofibre and a Single Quantum Dot Operated at Cryogenic Temperatures. [PDF]

Sci Rep, 2018
AbstractRecent progress in quantum nanophotonics brings novel ways for manipulating single photons in various nano-waveguides. Among them, one promising approach is to use optical nanofibres (ONFs), tapered optical fibres with sub-wavelength diameter waists.

Single atoms on an optical nanofibre

New Journal of Physics, 2008
We show that single-atoms can be trapped on the surface of a subwavelength-diameter silica-fiber, an optical nanofiber, without any external field, and that single photons spontaneously emitted from the atoms can be readily detected through the single guided-mode of the nanofiber.

Interaction of laser-cooled 87Rb atoms with higher order modes of an optical nanofibre

New Journal of Physics, 2015
Optical nanofibres are used to confine light to sub-wavelength regions and are very promising tools for the development of optical fibre-based quantum networks using cold, neutral atoms.
