The magnetic inverse problem for two stacked layers of sources
Michael T. M. Woodley, Thomas Coussens, William Evans +7
We present calculations that reconstruct electronic current densities in two stacked layers at known depths, using magnetic field data. Solving this inverse problem requires knowle…
Probing the Degree of Coherence through the Full 1D to 3D crossover
Robert Shah, Thomas Barrett, Andrea Colcelli +3
We experimentally study a gas of quantum degenerate Rb atoms throughout the full dimensional crossover, from a one-dimensional (1D) system exhibiting phase fluctuations cons…
A modular optically pumped magnetometer system
Thomas Coussens, Aikaterini Gialopsou, Christopher Abel +8
To address the demands in healthcare and industrial settings for spatially resolved magnetic imaging, we present a modular optically pumped magnetometer (OPM) system comprising a m…
An Environmental Monitoring Network for Quantum Gas Experiments and Devices
T. J. Barrett, W. Evans, A. Gadge +6
Quantum technology is approaching a level of maturity, recently demonstrated in space-borne experiments and in-field measurements, which would allow for adoption by non-specialist…
Additively manufactured ultra-high vacuum chamber below mbar
N. Cooper, L. A. Coles, S. Everton +11
Metal-based additive manufacturing (AM) represents a paradigm change in engineering and production methods across multiple industries and sectors. AM methods enable mass reduction…
3D-printed components for quantum devices
R. Saint, W. Evans, Y. Zhou +7
Recent advances in the preparation, control and measurement of atomic gases have led to new insights into the quantum world and unprecedented metrological sensitivities, e.g. in me…
Design of Magneto-Optical Traps for Additive Manufacture by 3D Printing
Yijia Zhou, Nathan Welch, Rosemary Crawford +6
A key element in the study of cold atoms, and their use in emerging quantum technologies, is trapping the atoms in an ultra-high vacuum (UHV) chamber. Many methods have been used t…
Novel laser machining of optical fibers for long cavities with low birefringence
Hiroki Takahashi, Jack Morphew, Fedja Orucevic +3
We present a novel method of machining optical fiber surfaces with a CO laser for use in Fiber-based Fabry-Perot Cavities (FFPCs). Previously FFPCs were prone to large birefr…
Fiber-coupled single ion as an efficient quantum light source
Alex Wilson, Hiroki Takahashi, Andrew Riley-Watson +8
We have realized a compact system to efficiently couple the fluorescent light emitted by a single trapped ion to two opposing optical fibers. The fibers are tightly integrated in t…
Excitation mapping of whispering gallery modes in silica microcavities
Guoping Lin, Bo Qian, Fedja Orucevic +5
We report the direct observation of the electromagnetic-field distribution of whispering?gallery modes in silica microcavities (spheres and toroids). It is revealed by their excita…
Neodymium Photoluminescence in Whispering Gallery Modes of Toroidal Microcavities
Fedja Orucevic, Jean Hare, Valérie Lefèvre-Seguin
We report on light emission from high-Q neodymium-implanted silica microtoroids. Following the description of the fabrication process of microtoroids, neodymium light emission is a…
Observation of Cold Collisions between Trapped Ions and Trapped Atoms
Andrew T. Grier, Marko Cetina, Fedja Oručević +1
We demonstrate a double-trap system well suited to study cold collisions between trapped ions and trapped atoms. Using Yb ions confined in a Paul trap and Yb atoms in a magneto…
Transmittance and near-field characterization of sub-wavelength tapered optical fibers
Fedja Orucevic, Valérie Lefèvre-Seguin, Jean Hare
We have produced high transmission sub-wavelength tapered optical fibers for the purpose of whispering gallery mode coupling in fused silica microcavities at 780 nm. A detailed ana…
