Atom Interferometry on Atom Chips-A Novel Approach Towards Precision Inertial Navigation Systems (PINS) [PDF]

, 2008
Abstract : Considerable progress was made during the grant period toward establishing a chip based atom interferometer. At the beginning of the gBECi period, no coherent on-chip beam splitter had been demonstrated. During the funding period, we developed two area enclosing interferometers with demonstrated coherence preservation: one using optical ...

First Intel Low-Cost IA Atom-based System-On-Chip for Nettop/Netbook

2009 1st Asia Symposium on Quality Electronic Design, 2009
The paper describes a design IP-reuse methodology used in a new Intel Low Cost IA (LCIA) System-on-Chip (SoC) design, call Pineview (PNV). The PNV SoC is used in the next generation Intel Nettop/Netbook platform. The SoC chip integrates several Intel internal Intellectual Property (IP) blocks on the same die: mainly two Atom CPU cores, a Graphic engine,

Miniature Bose–Einstein condensate system design based on a transparent atom chip

Journal of Physics B: Atomic, Molecular and Optical Physics, 2016
We propose a new miniature Bose-Einstein condensate (BEC) system based on a transparent atom chip with a compact external coil structure. A standard six-beam macroscopic magneto-optical trap (MOT) is able to be created near the chip surface due to the chip's transparency.

High Efficiency Quadrupole Magnetic Trap Transport in Single Chamber Atom Chip System

Acta Optica Sinica, 2016
With a movable quadrupole magnetic trap (QMT) generated by two pairs of partly-overlapped magneto-optical trap (MOT) and transfer coils, a highly efficient transport of cold87Rb atoms to the atom chip surface is realized. By the QMT movable means of linearly increasing the current in the transfer coils but simultaneously keeping the current in the MOT ...

Atomic precision imaging with an on-chip scanning tunneling microscope integrated into a commercial ultrahigh vacuum STM system

Journal of Vacuum Science & Technology B, Nanotechnology and Microelectronics: Materials, Processing, Measurement, and Phenomena, 2021
In this article, we replace the Z axis of the piezotube of a conventional Ultrahigh-Vacuum (UHV) Scanning Tunneling Microscope (STM) with a one-degree-of-freedom Microelectromechanical-System (MEMS) nanopositioner. As a result, a hybrid system is realized in which motions in the XY plane are carried out by the piezotube, while the MEMS device performs ...

A chip-scale atomic resonator-based stabilization system for optoelectronic oscillator

2014 IEEE International Frequency Control Symposium (FCS), 2014
The optoelectronic oscillator (OEO) uses an optical energy storage element to achieve high quality microwave signals which are spectrally pure. But in some applications, the stability loss and large physical size become considerable problems. To solve these problems, we present an approach of building chip-scale atomic resonator-based stabilization ...

Wavelength tuning robustness optimization for a high-temperature single-mode VCSEL used in chip-scale atomic sensing systems

Applied Optics, 2022
In this paper, the wavelength current tuning characteristics of high-temperature-operation single-mode vertical-cavity surface-emitting lasers (VCSELs) for chip-scale atomic sensing systems are studied. Excellent wavelength current tuning robustness is helpful to improve the stability of atomic sensing systems.
