Photonic integrated beam delivery for a rubidium 3D magneto-optical trap

open access: yesNature Communications, 2023
Cold atoms are important for precision atomic applications including timekeeping and sensing. The 3D magneto-optical trap (3D-MOT), used to produce cold atoms, will benefit from photonic integration to improve reliability and reduce size, weight, and ...

Integrated DFB Lasers on Si3N4 Photonic Platform for Chip-Scale Atomic Systems [PDF]

open access: yesConference on Lasers and Electro-Optics, 2019
780 nm wavelength distributed feedback lasers have been integrated onto a Si3N4 photonic platform on a Si substrate and coupled into waveguides for laser locking to either a ring resonator or rubidium vacuum cell.

Trapping and coherent manipulation of a Rydberg atom on a microfabricated device: a proposal [PDF]

open access: yes, 2005
We propose to apply atom-chip techniques to the trapping of a single atom in a circular Rydberg state. The small size of microfabricated structures will allow for trap geometries with microwave cut-off frequencies high enough to inhibit the spontaneous ...

Sensitive Absorption Imaging of Single Atoms in Front of a Mirror [PDF]

open access: yes, 2013
In this paper we show that the sensitivity of absorption imaging of ultracold atoms can be significantly improved by imaging in a standing-wave configuration.

Optimal control for generating excited state expansion in ring potential

open access: yesOpen Physics, 2020
We applied an optimal control algorithm to an ultra-cold atomic system for constructing an atomic Sagnac interferometer in a ring trap. We constructed a ring potential on an atom chip by using an RF-dressed potential.

Ex vacuo atom chip Bose-Einstein condensate [PDF]

open access: yes, 2016
Ex vacuo atom chips, used in conjunction with a custom thin walled vacuum chamber, have enabled the rapid replacement of atom chips for magnetically trapped cold atom experiments.

Tunable one-dimensional microwave emissions from cyclic-transition three-level atoms [PDF]

open access: yes, 2010
By strongly driving a cyclic-transition three-level artificial atom, demonstrated by such as a flux-based superconducting circuit, we show that coherent microwave signals can be excited along a coupled one-dimensional transmission line.

Quantum state reconstruction on atom-chips

open access: yesNew Journal of Physics, 2015
We realize on an atom-chip, a practical, experimentally undemanding, tomographic reconstruction algorithm relying on the time–resolved measurements of the atomic population distribution among atomic internal states.

Microwave quantum optics with an artificial atom in one-dimensional open space

open access: yesNew Journal of Physics, 2013
We address recent advances in microwave quantum optics with artificial atoms in one-dimensional (1D) open space. This field relies on the fact that the coupling between a superconducting artificial atom and propagating microwave photons in a 1D open ...
