Journal ArticleDOI
A high-performance accelerometer with a fifth-order sigma–delta modulator
TL;DR: In this article, a micromachined accelerometer with fully differential structure has been fabricated to verify the effectiveness of higher-order electromechanical sigma-delta modulator.
Journal ArticleDOI
Pyramidal micromirrors for microsystems and atom chips
Michael Trupke,F. Ramirez-Martinez,E. A. Curtis,J. P. Ashmore,Stefan Eriksson,E. A. Hinds,Zakaria Moktadir,Carsten O. Gollasch,Michael Kraft,G. Vijaya Prakash,Jeremy J. Baumberg +10 more
TL;DR: Concave pyramids are created in the (100) surface of a silicon wafer by anisotropic etching in potassium hydroxide as discussed by the authors, and high quality micromirrors are then formed by sputtering gold onto the smooth silicon (111) faces of the pyramid.
Journal ArticleDOI
Integrated optical components on atom chips
Stefan Eriksson,Michael Trupke,H. F. Powell,D. Sahagun,C. D. J. Sinclair,E. A. Curtis,Ben Sauer,E. A. Hinds,Zakaria Moktadir,Carsten O. Gollasch,Michael Kraft +10 more
TL;DR: In this paper, the integration of small-scale optical components into silicon wafers for use in atom chips is described, and an on-chip fibre-optic atom detection scheme that can probe clouds with small atom numbers is presented.

Journal ArticleDOI
Atom chip for BEC interferometry
Robert J. Sewell,J. Dingjan,Florian Baumgartner,I. Llorente-Garcia,Stefan Eriksson,Stefan Eriksson,E. A. Hinds,G. Lewis,Prasanna Srinivasan,Zakaria Moktadir,Carsten O. Gollasch,Michael Kraft +11 more
TL;DR: In this paper, an atom chip that operates as a matter wave interferometer was fabricated and tested by ion-beam milling of gold evaporated onto a silicon substrate, showing that it can coherently split and recombine a Bose-Einstein condensate with good phase stability.
