TOM 11 Tapered optical fibers, from fundamental to applications

Using optical nanofibres to mediate cold atom interactions

Sile Nic Chormaic

OIST Graduate University, Japan

We discuss several recent advances related to optical nanofibres in cold atom systems, including two-colour dipole trap optimisation using an in-loop stochastic artificial neural network machine learner, upper bound limitations on Rydberg atom excitation due to localised ion formation, spectral lineshapes arising from the high intensity evanescent fields, and two-photon processes mediated via the evanescent field of the optical nanofibre

Highly excited (so-called Rydberg) atoms are the key ingredient of many quantum information

schemes. In this presentation, we shall theoretically investigate how spontaneous emission properties and van

der Waals interactions of such atoms are modified in the neighbourhood of an optical nanofiber with respect

to the free-space (vacuum) case. This work constitutes a very preliminary step towards the realization of a

quantum network based on atomic ensembles linked via optical nanofibers.

TOM 11 Tapered optical fibers, from fundamental to applications

Gas-pressure tuning of wavelength of photon pair emitted by Four-Wave-Mixing in Nanofibers

Agathe Bonifacio1, Sylvie Lebrun1, Maxime Zerbib2, Maxime Romanet2, Jean-Charles Beugnot2, Philippe Delaye1

1Laboratoire Charles Fabry, Université Paris Saclay, France; 2Institut FEMTO-ST, Université Bourgogne Franche-Comté, France

We present experimental results demonstrating the possibility to tune the wavelength of the photon pair emitted through four wave mixing in a nanofiber, using the pressure of a gas surrounding the nanofiber. Using Argon, a shift of idler wavelength of -1.1nm/bar is measured demonstrating fine adjustment possibility of emission wavelength, allowing to choose between different WDM channels.

TOM 11 Tapered optical fibers, from fundamental to applications

Non-reciprocal amplification of light using cold atoms coupled to an optical nanofiber

Sebastian Pucher, Christian Liedl, Shuwei Jin, Arno Rauschenbeutel, Philipp Schneeweiss

Humboldt-Universität zu Berlin, Germany

Optical nanofibers realized as the waist of tapered silica fibers can be used to trap and optically interface laser-cooled atoms. Building on this system, we experimentally show a novel scheme for the non-reciprocal Raman amplification of light. While typically either the magneto-optical effect, a temporal modulation or an optical nonlinearity is employed to break reciprocity, in our approach, this results from the spin of the atoms forming the gain medium. By taking advantage of the inherent spin-momentum locking present in optical nanofibers, we perform an experiment in which we set the amplification direction by a suitable preparation of the atomic spin state. Our approach is general and, suitable quantum emitters provided, could also be implemented beyond the optical domain of the electromagnetic spectrum.
