Collective emission of atomic nanorings around an optical nanofiber
J. Jiménez-Jaimes, S. Nic Chormaic, E. Brion
We theoretically investigate the collective emission of one and two circular arrays of two-level atoms surrounding an optical nanofiber. We show that the radiation eigenmodes of a…
Evaporation characteristics of Er doped silica fiber and its application in the preparation of whispering gallery mode lasers
Angzhen Li, Jonathan M. Ward, Ke Tian +6
The fabrication of whispering gallery lasers (WGL) is used to experimentally evaluate the evaporation rate (mol/m) and ratio (mol/mol) of erbium and silica lost from a doped fib…
Structural characterization of thin-walled microbubble cavities
Mohammed Zia Jalaludeen, Shilong Li, Ke Tian +2
Whispering gallery mode (WGM) microbubble cavities are a versatile optofluidic sensing platform owing to their hollow core geometry. To increase the light-matter interaction and, t…
Excitation of Rb Rydberg atoms to nS and nD states (n68) via an optical nanofiber
Alexey Vylegzhanin, Dylan J. Brown, Aswathy Raj +5
Cold Rydberg atoms are a promising platform for quantum technologies and combining them with optical waveguides has the potential to create robust quantum information devices. Here…
Manipulation of polarization topology using a Fabry-Pérot fiber cavity with a higher-order mode optical nanofiber
Maki Maeda, Jameesh Keloth, Síle Nic Chormaic
Optical nanofiber cavity research has mainly focused on the fundamental mode. Here, a Fabry-Pérot fiber cavity with an optical nanofiber supporting the higher-order modes, TE01, TM…
Direction-dependent coupling between a nanofiber-guided light field and a two-level atom with an electric quadrupole transition
Fam Le Kien, Sile Nic Chormaic, Thomas Busch
We study the directional dependence of the coupling between a nanofiber-guided light field and a two-level atom with an electric quadrupole transition. We examine the situation whe…
Interaction of two Rydberg atoms in the vicinity of an optical nanofibre
E. Stourm, M. Lepers, J. Robert +3
We consider two rubidium atoms, prepared in the same S or P Rydberg states near an optical nanofibre. We determine the van der Waals interaction between them and identify novel fea…
Rubidium atom spectral lineshapes in high intensity electric fields near an optical nanofibre
Vandna Gokhroo, Fam Le Kien, Síle Nic Chormaic
The integration of cold atomic systems with optical nanofibres is an increasingly important experimental platform. Here, we report on the spectra observed during a strongly driven,…
Blue-band frequency comb and photodarkening in silica whispering gallery microresonators
Ke Tian, Jibo Yu, Fuchuan Lei +4
To date there are extensive studies of optical nonlinearities in whispering gallery resonators (WGRs) in the near and mid-infrared wavelengths. Pushing this research into the visib…
1.6 GHz Frequency Scanning of a 482 nm Laser Stabilized using Electromagnetically Induced Transparency
Krishnapriya Subramonian Rajasree, Kristoffer Karlsson, Tridib Ray +1
We propose a method to continuously frequency shift a target laser that is frequency stabilized by a reference laser, which is several hundreds of nanometers detuned. We demonstrat…
Optical trap for an atom around the midpoint between two coupled identical parallel optical nanofibers
Fam Le Kien, Sile Nic Chormaic, Thomas Busch
We study the trapping of a ground-state cesium atom in a small region around the midpoint between two coupled identical parallel optical nanofibers. We suggest to use a blue-detune…
Spontaneous emission and energy shifts of a Rydberg rubidium atom close to an optical nanofiber
E. Stourm, M. Lepers, J. Robert +3
In this paper, we report on numerical calculations of the spontaneous emission rates and Lamb shifts of a atom in a Rydberg-excited state lo…
