Abstract
The design and characterization of a two-axis rotational micromirror is explored. The mirrors were fabricated using a commercial microelectromechanical system (MEMS) foundry service, known as the multi-user MEMS processes (MUMPs) foundry service. The prototypes were then characterized using a phase-shifting Mirau interferometer. From these results, it was shown that the MUMPs process can be used to create satisfactory designs for rotational micromirrors with tilt angles in the range of 0-23 mrad and control voltages in the range of 0-30 V. In addition, the behavior of these mirrors was shown to fall within 5% of the values predicted by the theoretical models for the devices.
