Pyramidal micro-mirrors for microsystems and atom chips
M. Trupke, F. Ramirez-Martinez, E. A. Curtis +8
Concave pyramids are created in the (100) surface of a silicon wafer by anisotropic etching in potassium hydroxide. High quality micro-mirrors are then formed by sputtering gold on…
Microfabricated high-finesse optical cavity with open access and small volume
M. Trupke, E. A. Hinds, S. Eriksson +4
We present a novel microfabricated optical cavity, which combines a very small mode volume with high finesse. In contrast to other micro-resonators, such as microspheres, the struc…
Cold atoms in videotape micro-traps
C. D. J. Sinclair, J. A. Retter, E. A. Curtis +5
We describe an array of microscopic atom traps formed by a pattern of magnetisation on a piece of videotape. We describe the way in which cold atoms are loaded into one of these mi…
Integrated optical components on atom chips
S. Eriksson, M. Trupke, H. F. Powell +8
We report on the integration of small-scale optical components into silicon wafers for use in atom chips. We present an on-chip fibre-optic atom detection scheme that can probe clo…
Micron-sized atom traps made from magneto-optical thin films
S. Eriksson, F. Ramirez-Martinez, E. A. Curtis +4
We have produced magnetic patterns suitable for trapping and manipulating neutral atoms on a m length scale. The required patterns are made in Co/Pt thin films on a silicon su…
