Gollasch, C O, Moktadir, Zak, Kraft, Michael, Bagnall, Darren, Trupke, M, Eriksson, S and Hinds, E A (2004) A three-dimensional electrostatic actuator with a locking mechanism for a new generation of atom chips. Journal of Micromachanics and Microengineering, 15, (7), S39-S46.
This is the latest version of this item.
A micromachined three-dimensional electrostatic actuator that is optimized for aligning and tuning optical microcavities on atom chips is presented. The design of the 3D actuator is outlined in detail, and its characteristics are verified by analytical calculations and finite element modelling. Furthermore, the fabrication process of the actuation device is described and preliminary fabrication results are shown. The actuation in the chip plane which is used for mirror positioning has a working envelope of 17.5 μm. The design incorporates a unique locking mechanism which allows the out-of-plane actuation that is used for cavity tuning to be carried out once the in-plane actuation is completed. A maximum translation of 7 μm can be achieved in the out-of-plane direction.
