To verify the effectiveness of a higher order electromechanical sigma–delta modulator (ΣΔM), a micromachined accelerometer is fabricated. The in-plane sensor with fully differential structure has a mechanical noise floor below 1 μg Hz−1/2, sta

We have fabricated and tested an atom chip that operates as a matter wave interferometer. In this communication we describe the fabrication of the chip by ion-beam milling of gold evaporated onto a silicon substrate. We present data on the quality of

Ultracold atoms can be manipulated using microfabricated devices known as atom chips. These have significant potential for applications in sensing, metrology, and quantum information processing. To date, the chips are loaded by transfer of atoms from

Recent experiments demonstrated single-atom detection using microscopic optical cavities. Here we present an optical micro-cavity whose length can be tuned using an electrostatic comb-drive. This design is suitable for integration into a silicon atom

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 onto the smooth silicon (111) faces of the pyramids. These mirrors show

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 clouds with small atom numbers. The fibres can also be used to generate m

Electrostatic actuation is a promising approach to compensate for misalignment of bonded, multi-layered microsystem devices. The present work discusses the performance of electrostatic actuators used for in-plane misalignment compensation in an atom
